hey gang, im looking for a good track setup. ive looked through quite a few threads and couldnt find my exact setup in a track setting, so im just gonna ask. im running a complete e36 m3 strut/brake setup in the front and z3 1.9 hub in the rear. my suspension setup is billstein sports with h&r race. im looking to run kosei k1's, perhaps 16x7.5 et38 with 225 45 16's. im not ruling out running 17' k1's, but it seems to really limit tire options, being that i would want to run 225 35 17s'. any other people running k1s in this size or another size that they would recommend more with a similar suspension setup. i dont want any rubbing, but it would be nice to have a big patch of rubber on the road. thanks in advance.

You can go with either K1. The standard 17x8.5 +40 should work well with a 235/40/17 and a flat fender roll in the rear.

I know this has been answered probably 10 times, but I'm honestly having trouble finding a definite answer, i'm trying to run 16x8 xxr 002's ET 0 while lowered on coilovers. I'm planning on buying 205/45/16, but saw a few 205/50/16's that caught my attention as well, I want to make sure i'll just have to roll rear fenders, the fronts should be fine from what I understand? This is on a late model 318is.

Don't run 16x8 +0 XXRs. They will fit with massive work (very stiff springs, fender pull front and rear, 195 tires) but then you'll likely end up with ugly chipped paint. And by the time you clean all of that up and make it work, you could have afforded a nicer set of wheels that fit properly.

My $0.02.

Ah, not what I wanted to hear...I can always adjust the height a bit, thanks though, that's a huge help!

my car is lowered and is currently rolling on 16''s i want to buy some cheep wheels i can buy to fit on my car for the winter what should i do...i have bottlecaps but the regular size tire is too big it will rub what can i do? can i put sum smaller tires on it?

[jsantose30]

would 15 by 8s fit on e30 325i?

spacers

After reading your response to 8mm spacers I want to get your opinion on this. I did a test fit with a friends tires.



These wheels are the 7.5X17 ET 25 with 15mm spacers, from the factory, with 235/40 R17 888's on a 91 vert with H&R Sports (Vert specific). I may run a little less expensive performance tire. There are no camber plates on the car but I have considered installing them. I also need to drop the front a little more. The tires sit out too far in the front so I want to reduce the spacer width and would like to know what you would recommend and which one's would you stay away from. I was going to space it out with washers for the test fit and then buy the appropriate spacer but figured it was better to ask here first. Thank you for all your help.

Cheers,

Jim

Buy 175/70/14, 185/70/14 or 195/65/14 winters and put them on your bottlecaps.

would 15 by 8s fit on e30 325i?

Sure. Need the offset to give you a real answer though.

So the final offset is +25 then? They look too far in to be +10 effective offset.

If they are +25 final, then you can't run any smaller of a spacer, except maybe a 12mm. Camber is your answer.

If you take the ET +25 (published by wheel manufacture with spacer included) and remove the 15mm spacer I think they would be ET +40 without any spacer. This wheel manufacture used the 15mm spacer to calculate the ET 25 wheel offset that they published. I have confirmed this by finding the center-line of the wheel and measuring to the back of the spacer where it contacts the brake rotor to the outer edge of the lip and subtracting the two numbers from one another. I think that if I ran no spacers I would have interference with the brake caliper but a 4 or 5 mm spacer would cause the wheel clear the caliper. Hope this helps.

still looking for an answer to my question on the previous page.

Figured you would have looked at the ARC-8 by now and seen that it only comes in one 4x100 offset - the correct one.

As for mesh wheel recommendations, no idea. Not the thread.

[Mullet Bullet]

how about 15x8.25 0 offset? will it poke too much

The whole question was geared towards mesh.
