As some of you fully realize I've waffled quite a bit on whether to keep the Suzuki and whether it's worth upgrading. Personally, I've held since I bought the car that the only thing it needed to be motoring nirvana (relative to being a hot hatch) was another 30 hp, 20 ft-lbs. of torque and a limited slip.

After some soul searching, a failed state inspection (tires at 1/32) and ECU options finally opening up, I decided "what the hell, I really do love this car so lets see where we can go." What follows is a Modification list that I would love to be critiqued and told what I can genuinely anticipate from the car. They are also listed in descending order of expected completion.

Rims: Replace factory 17x6.5 with wider, lighter rims.
BOUGHT!: 17x8, +45mm, 15.6 lbs. Kosei K-1 Racing/ TS version. Made in Japan.

Tires: 225/40/ZR17 General G-Max AS-03 (BOUGHT!)
Extremely well rated and recommended. I will be weighing the wheel/tire combo that's removed as well as what I am putting on, hopefully I'll manage to save some weight even tho I'm increasing the size.

TO DO's: In anticipated order of completion

Roll and pull fenders: Neighbor has a friend who does amazing work and for only $50 a fender. the fenders will be rolled then pulled to match the edge of the wheels/tires front and back. Should look nice and is preperation for...

Coilovers w/ Rear sway and skid plate: Teins with camber bolts and RRM rear sway, the Megans scare me (perceived low quality/lack of R&D) and while I found some Suzuki Sports online the price is steep and shipping/fitment uncertain. The skid plate is so I don't rip something out from underneath my freshly lowered car like my neighbor did to his GTI a few weeks ago.

Time frame for these: hoping by mid June at the LATEST.

Exhaust: Apparently there's a shop nearby that offers mandrel bent custom exhaust at a very very reasonable price (same or less than what you might pay for a bolt on mail-order system) I will be using the Magnaflow 14210 paired with either 2 1/8" or 2 1/4" (looking for input here!) I may also go with a high flow cat/s for the secondary/all the cats if the shop/feedback from here indicates there are good gains to be made from it and it can stay emissions legal/warranty safe.

Intake: Still doing a lot of data gathering here, Currently deciding between the K&N drop-in, RRM SRI w/ K&N filter, or a RRM SRI w/ K&N Typhoon (Looking for input here!) Are there other filters that are as efficient (airflow and filtration levels) that don't require me to **** around with the filter/oil/etc?

Dynotronics ECU Flash: Because warranty and power, and the piggyback looks like a disaster.

Time Frame: Hoping late fall at the latest.

Brakes: R1Concepts slotted rotors with Stoptech pads and RRM SS lines. (Not going drilled because drilled rotors = stupid/pointless/dangerous)

Time frame: Spring 2013?

ODDS AND ENDS

Lightwerkz headlights conversion: Would love em, maybe when I'm done with the performance stuff if I can find $1500ish laying around I'll go for it.

Polarized tint: I like tint, but hate what it does to night vision, hoping polarized doesn't do that? And I think silver windows on my silver car might look sharp. Or it'll look like complete ***, tastes are pretty subjective.

Short shifter: Yeah, maybe one day somebody will make something that works with the 6-speed.....

Upgraded clutch?

Any other ideas? comments? Suggestions?

Good you are sharing your plans, & glad you decided to stick withe SX4. It'll be great hearing about the progression.

As far as intake is concerned ... I hear the SRI alone may actually hurt, low end & improve top end. The idea of the typhoon, is interesting, but I don't know of any reliable opinions. I personally have the K&N drop-in, and no doubt notice more responsiveness, along with a couple more hp.

Have you thought about a header?

Here is info on the improvement made on an Aero, with 2.0. Believe it or not they dyno'd before & after a installing a ground wire kit, and found an increase of 3-5 HPs. Go figure. I have the hardware, but am up in the air as far as specific locations to run the cable's out from the battery.

i want to know how would a drilled rotor be dangerous? I mean they wouldn't use them in racing if they weren't. I heard that they tend to crack with time, but that's after 60K+ miles.

I have had the piggyback for 2 years and no issues with it, better mpg and power. I'm not telling you to go for that as I am gonna go for the dynotronics reflash eventually. Can't wait for a premium tune and 7000rpm limit that's invisible by Suzuki.

I'd go for 2 1/4" exhaust, I don't think you'll lose any power there and as far as high flow cats, they will help some but be prepared to replace them every few years to pass emissions as it's gonna be the same quality as cheap replacement cats you'd buy at parts stores. the header would be nice if you add a second cat as you'll delete the first one with it, but good power is to be had there.

The SRI if you extend it a bit and do an air box for the filter it will work pretty good. Personally I love my CAI and no the intake isn't that low, never had issues with it. I don't drive through deep water either but stock height it's at least a foot off the ground and about 3" from the front plastic water deflector. only thing that sucks is the filter has to go in from the bottom and you have to unscrew one bolt and one pin from the splash guard.

I wouldn't bother with an upgraded clutch unless you plan on drag racing it a lot and even then with a FWD and only 30-40hp more our cars don't need it.

your list looks pretty good, I'm sure others will agree that we want updates and pics when you get that stuff done.

Drilled rotors can crack, and they are not usually used for racing.

Drilled rotors are just for looks but slotted rotors might offer some improvement. However, they are more prone to cracking because you're compromising the structural integrity.

soslow
April 29th, 2012, 05:51 PM
Many moons ago my parents bought me a book all about brakes from a racing standpoint. (including setting them up etc. etc.)

Drilled rotors are a carryover from racing back before slotting was discovered. They are better than a solid surface but are inferior in every respect to a slotted rotor. The whole purpose of drilling or slotting a rotor is to allow gasses generated by braking to escape, thus preventing them from pushing the pad up off the rotor and allow "trash" to be swept clean from the pads. drilling accomplishes the gas escape very well but doesn't do a very good job keeping the pad surface clean. In addition it reduces the surface area of the rotor, significantly reduces the rotors strength, and cause faster pad wear from the edges of the holes, especially if they're not chamfered properly.

A slotted rotor does everything a drilled rotor does with better rotor integrity and pad life.

C/N: Drilled rotors might look cool but you're better off with slots alone.


Thanks for the suggestions, keep em coming. Wheels and tires go on this week.

chief2001
April 29th, 2012, 05:58 PM
ok ok ok ok, first off, slotted rotors wont crack, we're thinking drilled rotors here. Also, drilled rotors are only mainly used in racing situations but many cars come with them as standard equipment. Our cars will not need them since we wont be doing anything too heavy for them. If you DO get them, just note that you will likely end up replacing them WAAAAAAAAAAAAAAAY sooner than a slotted rotor since they do tend to crack and they need to be replaced if they do. So unless you want to risk replacing them frequently go ahead. Even good quality drilled rotors will get cracked sooner or later. Slotted will work best to keep the pads bitting well for autox but not necessary if you just get a good plain rotor and pad set with some better brake lines.

I've had stoptech slotted rotors for 40k and they still bite nicely. I understand your concern about drilled, but the slotted are good quality. I've even had a few track days on 'em along with a few autocrosses. And I commute almost 600 miles a week. They're holding up just fine.

what camber setting do you plan on running, more negative or close to stock?
Depending on how low you drop it I would recommend neg camber so the wheels dont rub.

That's what rolling is for if it's needed. The only reason i would deviate from the stock camber settings is for performance reasons, not fitment. The tires have absolutely no rub now.

I suspect I'll end up running some negative camber in the front to help elimanate or tame understeer and/or increase the cornering limits, however the swaybar may end up doing that anyway.

In short: My alignment will be done solely with performance in mind, not fitment.

The major thing holding back the SX4 from being a little go-cart is weight, weight and more weight. Keep going with the weight reduction while keeping the balance and you'll be golden. The balance of the car is quite good in stock form.

Don't go overboard with the coils and slam the car or else you'll always be battling understeer. Keep the front soft so you get some bite on turn-in.

I like the BRZ/FR-S better with the weight distribution almost perfect, sleek lines and better drivetrain. You get 200hp of a N/A engine whereas you need the turbo to achieve the 210hp of the Veloster. Another point is the CG (center of gravity) of the BRZ/FR-S is better than that of the Vel with almost equal weight when you are stuffing a rearwheel driveline and a larger displacement motor on the FR-S. Not to mention that the Veloster drives with the wrong set of wheels... ;)

I'm think FR-S because a) slightly lower cost of entry b) $1000 for being military c) likely more warranty preserving (and well engineered) TRD parts, potentially to include power adders.

It really chaps my hide to think I could be driving a FR-S within the next two months had I not spent the money on the Suzuki.

If you're interested in a couple more doors then don't look at the Veloster. It's got only one extra. :p

I also got a couple of kids (one's still in the oven), infants to be exact and I honestly don't think the SX4 is the right choice for babies either. I can barely fit a front facing car seat in the middle much alone two car seats on either side. Not to mention how incredibly unsafe I find it to be for corner car seats do to its compact nature. Much of the reason I'm hunting for a family sized SUV.

Yup, the SX4 works okay for our single little guy, but if he gets a brother or sister within the next 2 years at least one of the SX4s will have to go. I won't be going the SUV or Van route, but certainly a sedan at the very least. Probably, keep my Crossover, and sell the Sportback...as the Crossover is more useful up here.

You guys are over stressing this way to much. My girlfriend has a kid and I function as his dad for the most part, including daycare doctors appointments etc. (we live together). Yes the FR-S is a small two door car but it does have a back seat. I can deal with the inconvenience a day or less. If I need to haul the boy around more than that I can just swap cars with my girlfriend (5 door Ford Focus, 5-speed; because yes I taught my girlfriend to drive manual and then she bought one).

This is a once every 10-20 years car, for me it's the Porsche Cayman I've wanted for ages but can't afford. Furthermore if people don't buy these cars the auto industry will wait another 15+ years to produce something else like it. That's what has happened with most of the best Japanese sports cars.

If I at all can I'm buying one of these. Everybody should get what they're passionate about once in their life, damn the torpedoes.

June 25th, 2012, 09:30 AM
The FRS and BRZ are not (quite) the same car. I've been in both raced at the limit, and they behave and handle differently (yes, I've spun both). The interiors are also pretty different. Also, the FRS has an 86 logo in the side that I swear looks like a swastika. You can't unsee it (^_^).
Personal preference will dictate your fave, and soslow's reasoning behind the scion is rock solid, but I love the subaru badge and really liked the BRZ's interior. If they made a TR (stripper) version instead of just "too much stuff" and "WAY too much stuff" trim levels I'd have driven one to work today. I don't need the nav or the fancy shcmancy stereo, I just want power windows, cruise control, and as much feeling through the pedals and steering wheel as possible.

Kids - No rear-facing seats in the toyobaru. They just won't work. Front-facing will work just fine, though, and that's my plan. As far as the SX4 goes, you can get two rear facing seats in if the driver's really short, but otherwise one front facing and one rear facing works just fine. I do it every day. I don't think you're supposed to put LATCH seats in the middle anyway, are you? In any case, our cars are a lot bigger on the inside than they look on the outside.

--e

P.S. if you have two kids that are young enough to be rear facing at the same time, you have my sympathy! I have a hard enough time keeping up with mine at 1 and 5, I can't imagine two under 2yrs!
