fender roller didn't work for me on the aluminum fenders. had to use a hammer and dolly.

 

I had a buddy who does a lot of fender rolling do it for me but he was pulling the fenders pretty hard but gradual to get as much pull as I needed. Its rolled about the top 35-40degrees if I had to guess. I know the pull is around 3/4".

Attached pic is right after rolling back when I think I had -3.5* camber. It just touched the fender at times but now with -4.2* we pretty much clear no problem. Only place we rub is inside fender and the liners in places.

 

Thanks for the picture. Do you have any pictures from the underside? I was using a lot of heat as well as going really slowly with the fender roller and even had a 2nd set of hands to help stabilize the fender from flexing. I was slowly able to roll the lip but then it just cracked on me.

I managed to get in contact with Evodave and he sent me one of his kits but with a 10.5 +30 wheel and 25mm spacers this new setup sticks out an additional ~46mm than my previous 9.5 +38 255 setup.

So according to my calculations, I will need just about anther .5" which means rolling or cutting should be perfect. Just not sure I want to break another fender trying to roll it and cutting means I may not be able to use fender liner...so yeah Im at a loss.

 

Do you need that much spacer for strut clearance? The NT01 will clear the brembos without any spacers.

With my buddies setup being real similar to mine but he's on NT01s, We were thinking 10-15mm would be a good setup to still get the camber needed.

Ill try to remember to get a picture of the inside of my fenders today after work. No guarantees though, a newborn is turning out to be a bigger distraction than I anticipated

 

No worries a newborn certainly take precedent over some slappy on the interwebz, lol

But to answer your question, I have no idea this is solely basing it off other's feedback which as we know its tricky given all the other variables. But my concern for going with a smaller spacer is that it was going to limit steering wheel articulation which sounds crappy IMO.

I figured if some of you guys could pull it off without an evodave fender mod then I should have no issues.

I won't know for sure until I mock everything up but for now my Ohlins are at OhlinsUSA my wheels are sitting in the basement tires in the living room and spacers on my work bench. So until I get the struts back and mount the tires I won't know for sure. Im pretty much out of time though so the next couple weekends are going to be quite hectic. It's looking like my first few events may be on totally cooked 255 Zii's.

 

So I put the 275's on in preparation of my Track Day this Saturday. I actually rolled the car out of the garage and right away I had a problem I did not expect. The tire rubbed the back of the front wheel well when turning. I got it back in the garage and took a little hammer massage to the inner fender tabs to get them out of the way. Maybe I am just too low. Also just an FYI. A Spec 255 R6 is the same width as a Regular 275 R6. The 275 is just taller. So not gaining much but tire height with the non-spec 275 just some height.

 

So Im just about done fitting these wheels, just waiting to get a part back from being welded and then I will take the car out for a spin.

But anyway the rears fit, I pulled the coilover off and put the wheel through its entire stroke and its finally good to go! This required a strategic slice with the cutoff wheel and then I hammered the seam/corner flat as recommended by one of you on here. I'd have to go back through the thread and see who told me that but whoever it was thank you that was exactly what it needed!

So my only other uncertainly now is in regards to the front. After test fitting with a 25mm spacer I was having major fitment issues with the front of the sideskirt however I had plenty of space inward. So I ended up having my spacers machined down to 18mm which still provides me with ample inward clearance but I can't quite make it lock to lock.

It has just the slightest amount of rub down by the side skirt. I ended up removing my mudflaps to provide a little more clearance but it is still just barely rubbing. It may work itself out but I would love to do some minor trimming if possible. The only catch is that it seems I'd need to trim my sideskirt pretty much right where it bolts up so Im concerned about it staying on there... which specific fender tabs did you trim? Do you have any pictures?

Im so close to getting this all sorted out and I will be testing the new setup on Saturday and Sunday where I hope to come back and report all is well. Through this entire process I have learned a lot from all of you as well as just getting in there and doing it. I really appreciate the feedback you guys have provided and when i have a moment I'll come back in here and post up my findings and specifics to what worked on my setup and what didnt. While some is vehicle specific a lot of this stuff carries over from car to car so I hope to be able to assist others down the road when they want to take the plunge to fit these wheels.

 

Same issue I had which was un expected. I use a hammer to ben the mounting tabs in enough to get clearance. Still not 100% no rub but close

 

With the perrin PSRS offset bushings it moved my wheel far enough forward that rubbing hasn't been an issue with 285s on 18x10 RPF1s +38 w/20mm spacer. I think I get a small bit of rub with my 275 RA1s on the same wheel now cause of the extra height though.

Of course that just shifts the rubbing to up front, so I cut the fender liner up to right about even with the frame rail. I left it a little lower on the passenger side to keep some tangentially flung pebbles/rocks from hitting the oil cooler.

Next year I'll be running the Hoosier A7 295/30/18 which is a touch taller than the 285 but not as tall as the 275/35's so I might have to do a bit more work but will still be tucking them under stock fenders even on a 10.5" wheel.

 

Yeah I ended up massaging it a smidge but Im a little scared of those stupid brittle aluminum fenders given my track record so I kept it mild. It is just barely skimming the side skirt now but I think Im going to leave well enough alone.

I took the car out to my favorite test spot last night for some road deflector slaloms to try and see if I would have any rubbing with bushing flex and things that are hard to replicate without driving and so far so good! The true test will be over the weekend but I'd love to focus on my driving vs if my tires are rubbing. I think a hammer will be added to my tool box this weekend though...
I tried some test fitting with my winter suspension setup which still had my PSRS on but stock top hats and it was hitting bad on the front fender liner and even the front corner of the lip. With my coils and my CDR plates dialing caster in up top allowed me to recenter the wheel. If I took out a little caster up top it prob wouldnt hit the side skirt but then its hit the front. Im being really picky now though since my rubbing is so negligible and I can basically go lock to lock so I'd pretty much say they fit. This of course is on my 285/30-18 ZII star specs so real rubber will prob fight me way more than my silly street tires.

But anyway thanks guys once again for your feedback I couldn't have done this without you all! The motorsports section of evom rocks!

Once I confirm all is well with my setup Ill try and snap some photos and provide a more detailed post of what specifically I did to fit my setup as another data point.

 

Please do! I'm not quite ready to order r-comps, but when I do, I want to go with 275's for my 17's. Maxxis makes the RC1 in 275/35r17, and my other options are all 275/40r17. I'd rather go with the taller tires if the fender work isn't too hard.

 

You guys are such an inspiration to me. Working on getting my car to a place where I can do HPDE and work my way up to maybe compete in some TT races. Its been my dream since I was in high school(I'm 32 now).

Even bought a pickup so I have a tow mule + family hauler.

Will be some time before shes track ready. Need tires and to get it all put together which will be no small task with these wheels. Not to mention shaking all the bugs out and getting the suspension tuned.

 

^^^Youve got some work ahead of you. Great project

Did you go with the: 18X10.5 +30 ?

 

NT03 18x10.5 +30. Have not decided on tire but going to go with 265 or 275 fitment permitting.

I have the evo-dave front fender mod, rears are pulled and rolled.

Also there is no suspension on the car so the hub/wheel is all the way flexed out in the photo.

I had CE28s on the car before but they are too pricey for track duty. Not to mention the staggered setup I was running means no tire rotation so tire cost would add up much more quickly.

Previous setup:
F/18x10.5 +18
R/18x9.5 +28

 

After reading this thread I might have some more work fitting the new tires on. Old setup was 285/30/18 ZII on RPF1 18x10. New tires are 275/35s RE71rs. May have to raise the car up a little but don't think it will be to bad. I'm hoping the added grip and sidewall will be worth the work.
