Will I need to roll my fenders?

rousegk7 · 08-14-2008, 12:21 PM

Looking to get some new rims, and was wondering if I will need to roll my fenders.

Suspension:
Bilstein struts w/ ST Springs

Proposed wheels/tires:
Front:
215/40/17
17" x 7.5" +35

Rear:
255/35/18
18" x 8.5" +35

probably.
You can get a better idea by comparing the particular tire you're going to throw on the back vs 9.5".

For instance, an re01r in 255/35 18 has a 10.3" section width (when mounted on a 9" wheel - it will actually shrink slightly mounted on a thinner wheel like yours).

10.3 - 9.5 = .8" / 2 = .4" of overhang per side of the wheel. That's approx 10mm of tire overhang per side. Even if half of that is eaten up by shrinkage due to using a smaller wheel, You're still on the verge of rubbing (1mm tuck from the outside fender edge for the tire assuming 5mm overhang).

cliffs:
probably, but if you're cheaping out on tires, it's more likely to fit since cheaper tires generally run skinnier.

Ok, well I decided to get the real work meister s1 2pc. And I am trying to figure out what offset I need to order.

They will be
Front: 17 x 8" +??
rear: 18 x 9" +??

What do you recommend for tires and offset to avoid rolling or rubbing.

EL PAALO · 08-15-2008, 07:14 PM

good for you. I hate fake bolts.

17x7.5 +35 MD Disk (34mm lip) with 215/40 17
18x9.5 +43 SL Disk (72mm lip) with 255/35 18
6mm tuck up front - tire sized evenly with wheel
2mm tuck out back - slightly stretched tire

caveats:
I like the front slightly more tucked than the rear.
I like a slightly stretched tire.

I am looking at the meister pdf atm, but am missing the md disk or sl disk, and also I dont see any 17x7.5 only by 7 or 8.

EL PAALO · 08-15-2008, 08:40 PM

lol, sorry.
I was looking at the ssr professor sp1 since that's what the rota d2 is a copy of ......

17x8 +35 A Disk (flush) 60mm lip
18x9.5 +43 O Disk (2mm tuck) 83mm lip

the slight tuck in back is a little insurance for no rolling. You may get by with flush in the back too since the 255 will be slightly stretched ..... just depends on how anti-roll you are.

You rock, now i just need to wait a few months to get the rims. Thanks again.

rousegk7 · 08-18-2008, 12:47 PM

Ok, getting ready to place the order for the rims, and I just want to double check to see if you are absolutely positive those are the right sizes and offsets. Thanks.

EL PAALO · 08-18-2008, 01:00 PM

I'm positive.
