So I've been reading a ton of threads and believe I've narrowed down what I would like to get. I would like some info from all if you if y'all don't mind. So here is what I have:

2009 FA5 NHBP

I want 18s for the look but am concerned about ride quality. I plan to get Eibach ProKit springs at the same time I purchase new wheels and tires. This is a daily driver though I plan on doing a few mods.

As for the wheels/tires I'm looking at:

17x8 235/40-17 +45mm
18x8 235/35-18 +45mm

From all I've read a 235 tire on ProKit should produce no rubbing at all. If anyone knows otherwise please let me know.

The last thing is the TPMS. I've read you can re-use the stock sensors in most cases. Would y'all recommend buying new sensors? TireRack offers sensors and their own reset tool for $280.

I understand some of these questions may be answered in other threads. I've read through 100s if not 1000s of posts in multiple threads to get to where I am now. I am looking to get better looks but also get some performance gains for future mods. (i.e. I/H/E/FP)

Thanks upfront for any input.

I think you should drive up to Dallas and pick up my 18x8 +35 RPF1s I have for sale :)

<3 07 since i have no tpms.

Dont worry much about rubbing if you're running a x8 45ot. Should be a very easy fit with the 235 tires. and for 18s get a 235/40, 35 sidewall would make it a rough ride and it seems you arnt looking for that.

If you have over an inch drop I would go for the 17's. They will still look nice but give you better performance than the 18's.

Thanks for all of the input.

With all the wheels I'm considering, regardless of 17 or 18 I will be saving 3+lbs. at each corner. In some combinations I'm looking at saving 5-6lbs. per corner. With 12-25lbs less of unsprung weight I hope to notice some improvements.

So y'all think a 235/40-17 would rub on Eibach Prokit? It seems in the sticky about wheel/tire combinations that work someone is running that size on Eibach Sportlines.

Another question I have is even with saving 3+lbs. at each corner is there that much of a difference in power with 17s over 18s?

I know 235/35-18 has some thin sidewalls but I don't mind a slightly harsher ride if I'm going to get more rubber on the road.

:yeahthat:

I had some 18's with a 40 side wall and noticed a significant increase in ride roughness over the stock 17's with 45 side wall. After about a year I ended up going back to stock.

Well, that might be enough for me to look at going with 235/40-17 on some 17x8 wheels.

I still can't seem to get a definite answer on a 235 tire rubbing with +45 offset and Eibach ProKit.

If you're trying to cut down on unsprung weight there's no reason to go with 235s. Just get 225s and take comfort in less unsprung/rotational weight and no rubbing issues, guaranteed. And if you want more grip, get better tires.

Yea, I'm thinking a big part of my frustration with the stock tires are their traction. As for the weight there really isn't a weight difference with 225 vs, 235.

The nice thing about a 235/40-17 or 235/35-18 is they are almost identical to stock overall diameter. A 225/45-17 or 225/40-18 has a larger overall diameter.
