Smile How is the ride with 18" wheel on WRX

When I am checking the wheels, I found myself falling in love with Rota Formula wheel. But they all come with 18" size. I am wondering how bad the ride quality is going to be if I go with a 18" wheel. Can any of you share your experience with me? Thank you.
Please give your opinion following two convcerns:
1. Ride quality/comfort
2. Performance in spirited driving/auto X

1. not that great because of the lessened sidewall on the tires
2. not as good due to added weight (unsprung?) [considering the same type and width tires are on]

I had some random brand 18s on my car for a few days, friend had em lying around. Its not dramatic, I think tires make more of a difference. Yes it could cost u some time in autox but the car wont feel slower at all. Also it should feel a little better in the corners

Agreed. Tires will make the most difference as far as ride quality goes IMHO. I've been running 18's for quite some time and have went through a lot of tires. The stiffness of the sidewall will make a dramatic difference on ride quality...

Thanks for the answers. I have one more question, which is
What will be the best wheel and tire size in autocross (in general)?
Will 18" do any good or bad? Please share your experiences, thanks.

I didnt like the ride quality of my old 17's, so I would think it would be much worse with 18's. Dont forget about cost, weight and damage possible due to the small sidewall. My 2 cents

i have rota tarmac 2 18's with yokahoma prada 2's on my 04 wrx and i love it. i have taken 25 mph turns at 65 mph on the inside and never passed the center line. those tires are like super glue and the ride is alot better than the civic si i had before that with 17's on it.

Again id like to emphasize the importance of tires on this issue. For ride comfort...at specified pressure, you really wont feel much of a idfference at all. On the corners they feel more repsonsive...gives your much more feedback as to wat your car is doing. The more tirewall...the more detached and elayed feeling i got. I have yoko parada spec 2's as well ^^^ and i love them...they are grippy as hell and they ar emounted on 18" racing harts. I had 17" rotas b4 with falken 512 ziex and compared to my current setup, they were a lot crappier....and at that time...i thot they (the 17") were good compared to the stock tires on my wrx.

But i honestly do believe that if i got some like advan r compounds...they wuolud be better than my 18" on parada spec 2's. Tires are the key in handling

I have 17" in winter, 18" in summer and just about when I get fed up with the 18s, it's time to switch. It's noticibly harsher on the 18".
The stupid thing that I will admit to right now, is that my car is quicker with the 17s but I guess I'm just blingin with the 18s. Don't call me a ricer, dammit!

tire pressure has alot to do with it as well. i have also noticed that larger diameter wheels with small side wall tires wear better. could be the way i drive though

Tires do make a big difference in your choice. On my stock 16s I put a set of crappy tires to get me through the winter, and they rode and handled horribly. Then I got some really nice tires for my 18s and not only did my handling and turn in improve dramatically, but my ride became more smooth and enjoyable, so don't skimp on the tires. Also, the difference between 17s and 18s in ride quality is almost nonexistent, but the style difference is better with the 18s. If you are totally into tenths of a second at the race track, 17s will most likely outperform the 18s, but you have to be pretty serious to make the difference worthwhile.

I havn't noticed much difference when I upgraded to 18's from my stock MY04 17's...If anything i found the ride quality on my 18's better then the 17's...

tire rack has both tire weights and rim weights listed on their website. it is possible to get lighter rims than stock as well as tires (those freaking re-92s are 21 freaking lbs!!!)

so just remember, it all depends on what you want to do. I say figure out what you want. a heavy tire also keeps your tires planted on the road more but provides a bumpier ride due to more sprung weight. more weight on the inside of the tire is better for acceleration, but not fuel economy. as you can see it becomes a science that can be really complicated. i say go for what you want.

p.s. i roll on 18 prodrive p1 (very strong rim) and bfg 225/40/18 bfg kdw. the ride is much better at 36psi but like 40 better due to better turn in and better acceleration. Also if you read on the sti forums, alot of them either switch to pinks or put more air in the tire due the struts being too hard.

Was using Prodrive PFF7's with 225/40's in the summer and Prodrive P7's with 215/45's in the winter. The ride is a little bit harsher with the 18's, but not terrible. In terms of performance, stick with sticky tires and light 18's that are strong and you will be fine.
