Default Need a track setup for my 2002 wrx

I need new wheels/tires and want the most cost effective setup as possible. I know very little about the tire and wheel side of suspension so please advise me for what would be best for my car for a reasonable amount of money. I do about 3-4 track days a year. 17" 18"? 225/45's? Please help!

Will rotas survive track usage? I hear they can fall apart, but this is usually from people that have 0 track experience so I don't know what to believe.

This is what I have so far for suspension setup.

KYB adjustable struts
Prodrive lowering springs
Perrin solid front and rear endlinks
Front and rear strut braces
I will have sway bars by the time track season starts up

Go with Rotas. You will be fine. I've been using them for years. Plus, if one gets damage, it will be easier and much less expensive to replace.

I would use a 17x8 or 17x8.5

a 245/40 should fit without rubbing(much)...those Prodrive springs are 'street' springs and are a bit soft for 'track'...with a bit of a roll and camber bolts a 255/40 should fit

consider stiffer springs...and dspec shocks in the future as an upgrade

The new Rota DPT wheels are 17x9 and come in at $850 a set, and they'll clear pretty much everything but a 355mm BBK, which is is nice if you decide to go to a larger brake kit later in life. Otherwise a nice 17x8" set can be had for $650. Plenty of guys track Rota's without issue.

As US said your springs are not the best for track, but to go to a stiffer spring you're really going to have to change out the struts as well. Not to expensive to do that though if you take your time researching.

With that said though any time on the track is worthwhile to improve your driving skills. Car is only part of the equation

I actually have been running stock springs all year, so I don't even know what the prodrives will be like, I assume they will be an approvement. I got them for $50, so I hope the prodrive springs are worth at least $50 at the track compared to stock.

It sounds like I should be looking at a 17x8 with 225's? Is a wider tire always better? It seems like it might be less responsive. What should be my goal for tire width be in terms of not costing a fortune. I am lucky enough as it is to be able to hit the track while I'm in college.

A 235 or 245 on an 8" wheel is perfect. 225 is a little narrow on that width. The prodrives will be an improvement, but nothing huge.

well what springs would be a better choice for 02-03 struts for track use? I couldn't even find another option. Please hurry and tell me before I put the prodrives on. I realize that coilovers or nicer struts would be better, but that isn't an option at this point.

But there has to be a size that will perform best on an 8" wide wheel, that is what I am trying to understand. I thought that if you go too wide with a tire on a wheel that isn't wide enough, the sidewalls would wear out super fast and it would yield bad performance

the oh boy is because we keep telling you that a 235 or 245 is FINE on an 8 inch wheel. A 255 is when you start getting wide. Have you read the stickies at all? Also look in the motorsports forum for the wide tire talk thread.

Buying coilovers is a VERY Vague statement. You could spend $1K to get a set of springs & struts that could match or outperform coilovers in the same price range. It is ENTIRELY dependent on WHAT the goals of the car & driver actually are. There are quite a few people that think that they HAVE to get coilovers when in fact that is just not true. Remember that coilovers are a lot more involved & don't tend to last as long as a spring & strut setup. Yes you have the variability options available with the coilovers, but I would not be surprised if MOST street driven coilovers are simply thrown on the car and never really touched or properly adjusted. Also what works well for a setup for 1 car may not be a very good setup for another as different cars behave differently & different driving styles can DEFINITELY affect the way the car should be setup.

I have some 17x8.5 Rota Slipstreams with some 255/40/17 RT615 tires if you are interested. I was going to use it for next years season but I think I am going a different route!

And over all, you are going to be looking for a light wheel that will get over your brakes. The tire is what is more important!

If you are looking for a cost effective setup I highly recommend Rota wheels. The new Rota DPT is very popular for track/autoX due to the nice size/fitment, low wheel weight, and affordable price. For aggressive street/track driving these wheels come in a 17x9 +42 fitment for Suby's. With this wheel you can easily run a 245/40/17 tire (only requires rear rolled fenders) and it will perform very well. I run this setup on my car right now with 245/40/17 Bridgestone RE-01R's and it's a blast to drive.

17x9 +42 5x100/114.3 (dual drill), only 18.9 lbs.

very true - though I disagree slightly: if you're blindly slapping on coilovers it's ok, just make sure to consult a knowledgeable track guy (this is where mechanics who also track their cars are golden), and have your mechanic/track guy tune it for your liking.
