the strut tower mod is simply removing the factory guide pins, and does not require any bolt kit. if there is some other mod going on, be sure to get detail and post them. zpost would be glad to have more information.

also, you could use 4 front wheels on carefully selected tires. you would still need one helluva neg camber setting for the front though.
i just first want to say that i've been running a 225x35x20 on a 20x9.5 on my other car (vip sedan/toyota crown in japan) for a long time and obviously i don't track it but it works just fine and i do drive 'spirited' as they say,, had the same size tire on the same size rim on my last car 05 lex LS430 for like 3 years and it was just fine too.

i've also run 245x35x20 on 10.5" wide rims no problems and presently run a 265x30x20 on a 11" wide rim on my crown without any issues. these are mild to medium stretches in the vip community, but we obviously don't track our cars

i'm glad you haven't had issues, but your experience does not convince me that fitment is safe.

what kind of pressures are you running in those?

45 ish. on my daily fronts 225x35x20 on 20x9.5
45 ish on rears 265x30x20 on a 11"

higher when i had more of a stretch at one point i did hit a pothole and broke the bead on a 245x35x20 on a 10.5 wide rim... all of these were on on nitto 555's and one pair of general exclaims

i once tried to stretch a toyo expensive tire 255x30x20 on a 10.5 wide rim and this stretch seemed the most aggressive in appearance and in trying to get the tire to mount. i guess the tires themselves really can make or break a stretch; some stretch better than others.



right now i'm trying to get some ballpark specs for when i finally get some wheels for my new to me z4. my other car is really aggressive so i am not going for this look again intentionally but a lot of the wheels i really like are in the 5x114.3 bolt spacing and the smallest adapters i have found are 15mm so that makes all the wheels i find in the 114.3 spacing 15mm more aggressive when i put them on the z therefore limiting the selection severely. at this point i'm thinking 18's or 19's, but would prefer a set already in the 5x120 and fairly light so i don't have to put on some heavy rims + adapters + extra lugs etc etc...

So I'm looking into sizing them correctly etc.
Thing is, I'm not sure what different suspension geometries are around, some people talk of zhp and sport suspensions, but I'm not sure what identifies either on the car. I think I'm running stock although my car does have the sport and premium packages if that makes a difference. Is there a simple way for me to check what suspension I have ie go measure under bumper and it should be x inches high off the ground kinda thing?
Any ideas?
I have the same car, and the same exact question. Im looking for a cost effective upgrade. Looking at BBS LM-R reps 19's 8.5front, 9.5back. But worried about stance not being right on my stock sport package suspension. So looking for a cheap set of springs? that lower the stance but keep the comfortability of daily driving.

THANKS IN ADVANCE!

Looks like CSL knockoffs, weight seems to be on the heavy side.

Absolutely a knock off but the style I want.

What would be considered light for this size of wheel?

Josh those are super light.
I know unsprung weight is important but does 5 or 6 lbs really make that much difference I do not know the physics behind that?

It's less weight for the suspension to move around. So in a word, yes.

Some say the rule of thumb is 1 lb of unsprung weight equals 10 lbs on the car. I think that's a bit exaggerated, but the ratio is at least 1:3 or 1:4.

not sure about those weights I don't think a 9" wheel can weigh only .2lb more that an 8" wheel

I did end up buying these wheels for 2 reasons, price and style.
A little heavy but the weights are as advertised on the company website.

The wheels are Linea Corse LC 818. http://www.wheeldude.com/catalog/pro...oducts_id=6410

But I got a local CNC company to shaved off the centers for a higher offset since the original offset is for E9x. So now the fronts are ET34 and the rear ET41. But with a little more agressive negative camber in the rear I guess it would have cleared the fenders with ET37. Especially if the fenders are rolled.

The fronts are more of an issue. With the tires I run and 8.5" w/ET34 it rubs alot. So I have installed adjustable camber plates to clear the fenders. Now its good. Maybe it would have been better with 225/35.

The tires are Michelin Pilot SuperSport 235/35-19 and 265/30-19.


If you like this look you could check out for example the Miro 111. I know there are also some other brands that have almost the same look.

Hi guys, could please someone tell me if 8,5Jx18, ET34 would be ok for E85, factory setup?
I'm positive for rear, but with doubts for front.

Thanks.

the picture of the black coupe above has 8.5 e38 on the front and 9.5 e 42 on rear so you would be 4mm further out.
