Default Tire and wheel combo.

Got a new '04 black STi recently. But I hate the ride. It's got 18's on it right now and it's lowered.. rides like crap. So first off I'm looking at getting some rims and tires. And then, depending on the ride, maybe trade someone springs to raise it back up.

How big is the jump for ride quality from a 17 - 18? I wouldn't mind keeping a good looking 18 if it rides well.

I was thinking about getting some Work emotion XD9 Bronze, but I saw the G- forces were similar for a lot cheaper. I live in ID, so I need some good all-season tires with em. I've been looking at getting the following setup: 245/45ZR17 Bridgeston Potenza RE960AS Pole Position.

How would that ride? And what about clearance with the Brembo's and side panels?

Any pictures of bronze rims on black cars? I've looked around and found a couple...

If you live somewhere with snow you could always get 2 sets of wheels. I have 18x8 Rota Tarmac III's for the SVX(will also go on my Impreza when i swap hubs to STi's 114.5) I run snows on my stock wheels. 18's are a good ride.

I would just put snow tires on my stock tires if I had them. But I only have those 19's which wouldn't work out too well. So I think I'm just going for some A.S.

The Tarmac 3's look pretty similar to the g-forces.. but seem abit cleaner cut. Any noticeable differences besides $50?

It's all preferance. If i get another seperate set for my other car I want to get a set of G-Forces with a like +35 offset. http://forums.nasioc.com/forums/show....php?t=1560585 Check through this thread to look at a lot of wheels that may be something you're looking for.

Realized mine are actually Primax's 618's 18" with toyo proxes4 215/35zr.

So either 18"s ride like crap and I need 17"s or the problem in the lowering set up.. Which I haven't been able to identify.

whoever you bought the car from is a retard. 18s with 215/35s? not only is that narrower than oem, but also shorter.

if you want better ride quality, look at a set of 17s. being lower doesn't help either as your strut travel is limited, as is your suspension's ability to soak up big bumps.

If you are going to run them all year, 17's for sure. Not sure how your roads get in the winter, but with all the potholes and bumps in NE, life with 18's would be rough.

Looks like I'll probably get 17's then since they'll be used all year.

Anyone know how I could identify my lowering kit? And would it be easy, cheap to trade someone for either taller performance ones, or stock?

Excuse me for misreading the tiny, black, and dirty writing on the tire. Wow.

Take it with a grain of salt. If you end up going to 245's I would suggest investigating the 245-40-17. I am not much of a fan of the 45 aspect ratio on anything past 215. Just my two cents.

That makes it slightly more low profile, correct? and would I have clearance problems?

With the perrin lowering setup, it's pretty low... I plan to either go back to stock or performance ones that would raise it back up.

If you had stock size of 225-45-17 you should have no problem with 245-40 17 as far as OD is concerned. Because of the width you will need to roll the rear fenders, how much depends on the offset of the wheel and what you are going for. I wanted 17x9 wheels under my wagon while retaining the +55 offset, obviously that is not possible because I do not have nor could I get the clearance on the strut side, so my offset was determined by finding a balance with the geometry of the suspension as a system being my first priority. So what you will have to do to make the width fit is directly proportionate to the offset you choose.

OD as in odometer?

Alright, so say I want either 17 or 18 inch G-forces. I need to have a smooth ride and control in the rough Idaho winters. I plan on getting Bridgeston Potenza RE960AS Pole Positions with them. I don't want to have to do any rolling of the fenders, or any of that kind of business. I love the look of an aggressive tire.. but don't want to go overboard with all the hassle. Don't want any problems with my speedo/odo either.

What would be my best bet of rim size and offset, as well as tire size?

And would that lowering kit be a problem? it's pretty slammed, but I'm planning on getting rid of it; just hoping on getting the rims/tires first..

OD as in outside diameter. the OD of our stock setup is 25". if you want a smooth ride, stick with 17s. it does make a noticeable difference.

17x8 +48 with 225/45/17 or 235/40/17 would be ideal and clear of any rubbing issues.

do you know what springs you have currently?

+1 for the 17x8 +48 with 235-40-17. Spring change would most likely improve your handling if they are "lowering" springs, though performance springs do lower the car some (most of them lower it 1" to 1.25").

They're hard to get a good look at. But my mechanic said it was some sort of Perrin setup. He didn't know if it was just springs or coilovers or what.

But they're all red, and the Perrin ones online are black... Some can be adjusted hight wise, can't they? That'd be perfect...

-_- So... we've narrowed it down, they're either coil springs or coilovers. At least they're not pieces of string cheese.

Are 235/40-17's going to be clear of rubbing even on Prodrive springs (stock struts) on an '07 wrx? I ordered some 17x8 +48 torques with 235/40's and I'm getting alot of people telling me that I'll rub...but I'm almost positive I shouldn't have a problem.

you should be fine. if anything, you'll rub on the rear fender lip, but i don't see that happening.

Got a good look at em today. Stock 04 STi struts are red right? If so, it looks like I just have the Perrin springs.





Here's why I can't get into parking lots...





And my Greddy exhuast scratched the other day while just driving down my city's main street.(came to a part with small ruts)

yup those are stock struts. looks like your rear fenders are rolled cause i see no evidence of that rubber liner on the lip.

go with a 17x8 or 17x8.5 with a 245/40/17.

If I were to get 245 with 17's I'd have to get 245/45/17. They don't come with 40 ratio. Probably cause they're all season. So that would: not rub, have same OD, and fit well-- without getting taller springs first? or should I got with a 235/45/17?

And I think G-forces come in 7.5 and 8. Would I have any problem/advantage going with one over the other?

Idk about the rear fenders being rolled.. But I do worry about hitting the rear fenders. It's already pretty close in the back.
