Will this fit? (width, offset and tire size Qs)

With these specs, will the wheels tuck in or perfect flush with the fender?

I am thinking putting the Eibach Pro-kit later.

Thanks.

These will not fit at all, since the bolt pattern is wrong. You need 5x100. You can use spacer adapters, but that effectively lowers the offset and it'll get ridiculous real fast. Or you could swap to 5x114.3 hubs, but I think they're hard to find now.

Otherwise, that size and offset has plenty of room and should be fairly flush with maybe a little poke out. See any of my multiple posts that state I had 17x9 +28 on stock suspension with 235/45 tires that run wider than normal, with no rubbing. I think you should put something wider than 215 on there, but I'm not into the stretch/poke thing.

Even with springs, I can't see any issues since Pro-Kit isn't that low.

Oh, I see. I will get the 5 x 100 instead.

Regarding the Eibach Pro-kit, do you guys use the stock shocks? Are the Pro-kit springs very hard? Will they damage the OEM shocks in the long run?

ProKit ride is excellent, stock shocks are up to the task especially for street driving.

Better damping is always better and Koni Sports are a great match for these springs.
I'm currently running the stock shocks but planning to upgrade soon as I do alot of track driving. They won't blow out the OEM shocks though.

Btw, the revised balance of the ProKit springs makes for a much more predictable drive, less tail-happy unless you induce it and very gradual shift. Love these. I'm even running them through the winter, no issues and better grip all around.

[Gps360]

What is the revised part number for the Pro-kit springs?

[Slick]

Revised??

Part # is 82105.140

Hello everyone! I really do appreciate this ongoing thread as it has been extremely informative! I plan on getting 18x8.5 +45 5x100 wheels -- what tire size would you all recommend? I currently have the Eibach Pro Springs installed so that's about a 1" drop on both front and back from stock.

That's gonna be pretty close to the strut, don't think you'll make it fit.

I have about 4mm clearance, you'll be about 0 unless you have very mild camber settings but you already have a 1" drop so likely at -1.5 already. If it fits and doesn't touch the strut, then you will likely rub the tires on the inner fender liner on maximum lock.

Ideal offset fit that size wheel is +35 to +40 on coils. With coilovers you can run a higher offset (less poke, more tuck) but still not ideal anyway.

245/35R18 is the best tire size for that rim width.

I have hit a wall trying to figure out what is going to clear on my car haha. I want an 18 inch wheel and since I am planning FI soon I need some more width. 8.5,9, 9.5...guess it depends what I can fin in the wheels I like. My car is on the pro kit springs on stock shocks and will be going to konis eventually. My biggest concern is I dont want rubbing but want to maximize width. What is a safe tire size and wheel width/offset with my suspension. Thanks a lot to the knowledgable guys on here because eve with my engineering degree I am still struggling to determine what will be best for me haha.

18x9 +35 done.

Can fit 255/35R18 square and even 265s in the rear if you want staggered (on your spring combo stated above.

[gord1895]

Really, so with being almost an inch lower and adding some camber and say a 245 tire all around the 18X9 +35 is a go? Thanks a bunch for some reason I was thinking I would either be rubbing the spring perch or sticking outside the fender a bit.

That's exactly what I'm running: 18x9 +35 with 245/35R18. Fits perfectly, great stance, does not rub anywhere. I also track the car extensively with no issues.
I also added factory crash bolts in the front for a bit more camber (so wheel rim is a bit closer to the strut), so I'm running -2.2 up front and about -2.0 in the rear.

[IAmNotTheDriftKing]

Alright, so I have decided on a 17x9 wheel with a 42mm offset. I was wondering on stock suspension how much camber can you add before rubbing. I was hoping to get -1.5 degrees.

Hey guys! 18x8.5 with 245/35 tires 1.5 inch drop, Safest offset? Just would like to know.
