You made the classic mistake. You went for power and ended up forsaking the chassis. Now you complain that you can't go as fast as you want. Suck it up and realize that it's your own fault. That's my opinion of your setup. The race car guys you talked to didn't say a negative word because they were being polite. I guarantee they looked at each other after you left and said "what the hell was he thinking, doing power first?" There isn't just one way to set up a race car, but undertiring the car is certainly wrong. By the way, 225s won't cut it. You'll need 245s or bigger. I hope you aren't incredibly fond of stock bodywork. |

wow.......i didnt go for big power, 230whp is hardly big, im not complaining about any of it at all so there is nothign to suck up. I enjoy every second on track with an underpowered wide tired car or an overpower undertired car. And telling me the race guys were talkin shit behind my back, not cool. I ask for advice they give it to me, real advice not the BS your posting. ![]() There is no need to tell me to suck anything up or deal with anything, i didnt critisize you at all when i responded to your post on here, simply explaining the setup. At least do some research on the tires i have on the car and the ones ill be running before you say one wont be enough for a certain setup. Or find out exactly what true race car builders have told me before you tell me they were callin me stupid for the order i did things. There is no eed to be so defensive, its ok, just make sure you know exactly what is expected of a race car and a budget and when you do finally know, deal with it.

I have played around with my alignment for the last 3 years, as of now I only auto cross, but here are my specs...
The car is a 91 hatchback, w JIC flta'2s 7/5kg/mm spring rates. 15x7 + 0 offset w/225/45/15's victoracer's (econo racers!) White line sway's front and rear with custom fabricted spherical endlinks (BTW the endlinks make a huge difference, much much more predictable...). 50% spherical bearings 50% poly... (soon to be all metal) Front camber) 3.7 negative ___ rear camber) 2.3 negative ... I have never been on a skid pad, but tire temp's are pretty even. I think you will need more or less camber depending upon Tires, and wheel rates. I have heard of other's running 5+ degrees up front and 3+ in the rear, but that effects braking. Front toe) 1/16-1/8" toe out helps turn in, makes the car much more responsive. Rear toe) 0 degrees__ I tried a little toe out a couple of times now, and the car is way to unpredictable, I don't recomend it. Toe in will help the car get the power down and help stabalize the car. I tried up to 1/8-3/8 toe in, which definetly stabalize's the car, but I like my car fairly twitchy for auto X'ing. Well thats my setup, hope that helps -Jason M P.S improvedtouringforum.com- look in the nissan section... thoose guy's know about the 240...Bob stretch did well with his 240 in ITA. You really need spherical bearings all the way around if you want to be competitive, reducing suspension bind is a big deal with 240's. (we have lots of bushings) Stretch ran on Advanced design double adjustle struts, with I believe GC's. Some (and possibly most) of the ITA guy's run without a rear bar, they say it make's the car more predictable... |

I like your setup, only thing is i havnt heard many good things about the JIC coilovers, but thats all i ahev heard, no experience here. I have never autocrossed, but i know the low speeds and sharp turns require a very touchy suspension setup. I plan to go with adjustable links with bushings, i need the bushings to absord some stress from the road (being that some courses are rougher than others). I havnt planned to run as much negative camber as you, maybe -2 deg all around. and for toe in/out, id like them at 0 becasue of the long banking turns i dont need the tires fighting each other at all for the speeds im moving at. I have talked to a few ITS or ITA guys before at VIR, most of them ran a basically stock setup, with coilovers and pillow ball mounts, but im not sure about all the links, i never had time to sit down, they were busy prepping the car for the races or qualifying track times. They are good to talk to about the ideas of the suspension, but i cant relate to them 100% because i plan to push more than twice their wheel HP once i get to comeptition, which means i need differnet breke, and tire setup then them. But their knowledge of suspension has been and will be helpful. Thanks for your advice and setup of your car, good reference, thanks jason.

heh, instead of -2º of camber, you should try shooting for more than -5º. the Stretchmobile still holds many track records for an ITA car, and he was running far more than the usual camber... which brings me to the next point. If you are serious about racing, and/or winning Spend money on a good data acquisition system before you start throwing money elsewhere. The data gathered from one 20 minute session can be worth more than a year's worth of racing without one, and when you add up all the entry fees/lodging/gas it is well worth the money. I am just learning about racing myself, I have started crewing for an ITA 240SX that also needs to get it's setup ironed out. But from hints I have gotten from real racers, it has opened my eyes to how wrong everyone here is...

I would have to agree with you though on power before setting the car up correctly. I am a much better drifter today than I would have been if I started with a high horsepower car. My car has a completly stock ka and I am doing almost everything before I do my swap and even after I swap the sr it will be almost completely stock with a stronger clutch and some bolt on's I would lots rather carry a lot of speed and be full throttle than have to modulate the clutch and throttle through the entire drift. edit: go bigger than 225's you will regret it otherwise. With a stock ka I can spin 225/45-17 mich pilot sports all day long especially 2nd or 3rd gear drifts. if you want grip go to 245/45-16's |

I never plan to go wider than 275 all around, i make my own fender flares that rivet onto the existing fenders and give me an extra 1.75 inches of clearence on each corner to fit the 17x10's with the 275/40 series tries i plan to run for competition. I used this car as a daily driver for about the past year driving to school work everything, I did the power because my first 240 had a blown motor so i swapped this in, then second 240 i got (this one) had a blown motor and a melted fusebox, so i fixed all that and slowly it got to the point is is today. I did mild suspension with grippy tires for how i have been driving on the track. I moved the tries up form the old ones i was driving on before, everyone seems to think that extreme traction is teh way to go with a track car, but to learn the car you have to actually learn what it can /cant do with or without traction. the small tires i used for the 4 track events this past year worked great, i dont complain, i simply say they werent enough for me to do my best. I am upgrading to the 225/50R16 Toyo RA1's, they are an R-COMPOUND TIRE!! VERY sticky for the track once heated up, i am not ment to go 100% throttle through every corner at every possible second, that not how you road race, so i dont need a relly wide tire yet until i upgrade my power some more. Drifting a a 245 tire is alot different from gripping with an r-compound, as around at race shops about r-compounds, for a car with my setup 225 is fine especially for the rim size i have (16x7.5). At the shop by me, some guy boughta 240 all setup for grip that came with brand new Toyo RA1's 245/40R17's, he traded them for soem used tres with far less traction so he could drift the car beasue the RA1's are way too sticky for drifting, so you need to realize that you 245 pilots are less sticky than my 225 RA1 R-Compounds, so a comparison cant be made between the two. DRIFTERS PLEASE READ UP ON R-COMPOUND TIRES BEFORE YOU POST ABOUT MY TIRE CHOICES!!!!! SPECIFICALLY "Toyo RA1" TIRES!!!!!

![]() I'm giving up on you. Lost cause, because you won't listen worth shit. Not only do you have no idea how much track time I have, but you don't know what my current profession is. |
