Got a RPF1's Square setup, need some advice
My car is making over 630 to the crank so I'm getting rid of my 19's. Great news I just got some RPF1's for my E55(I know its a first for E55 haha) , so they are 18x9 all around and 35 offset all around. Im not worried about the rear but how about the front. Would i like to have 275 all around so i can rotate my tires? YESSSS!!! Am i going to be annoyed if i have to get spacers? YESS lmfao! I would love to hear from someone who have done this setup. But i know that the fenders up front are very wide, my only issue is the 35 offset in the front will bring the car too close to the brakes, maybe a 30 offset is more ideal.

They will fit like that, but will look strange. Stock is 18x9 +36 R and 18x8 +30 F. Wider SL wheels are 18x9.5 +33 R and 18x8.5 +30 F - and fits just about perfect in the wheel wells.

stock is 39 R and 30F. My front rim is not a 8 it's a 9 so it will compensate for the extra 5mm. The rear will sit perfect. I'm just concerned about 275 up front

I have never heard of anyone running a 275 up front. If you search you may be able to find something. From stock wheels - the 18x9 +35 square will extend only 4mm in rear, and then 8mm up front. That is why I cautioned against it probably looking odd with a square setup. I would measure before setting your mind on them.

There's quite a few guys running 275's up front on the forums. I have the rims so they going on I'll know right away if they fit when I mount them. There is posts but nobody is giving up their offsets. A 35 in the rear will look more flush then a 39 et e55 rim. A 35 front on a 9 inch rim will be a little more flush then a 8 inch front 30 offset e55 rim because the e55 rim is a full inch smaller, that's why I'm using the word compensate. So I don't understand the looks part being off Bc the fitment will be very similar to a stock e55 maybe more wider looking. But the 275 fitting with my front rim offset is something I'm definitely questioning I may have to go 255 Bc it may rub on the inside only I get a spacer to push it away from the brakes. But 275 all around is definilty doable.

I don't mean to sound like an idiot but what are the advantages of a square set up? If your suspension is in good condition there shouldn't be any significant asymmetrical wear to require frequent rotation and the increased front to rear ratio will increase understeer won't it? Running better tires (if possible) is always the most significant improvement to traction.

My thought is still that the fitment will look goofy - if you've ever messed around with spacers, 4mm vs 8mm is a discernible amount. Your front will be basically flush, while the rear will be just about the same as stock, and sunken back into the fender. Hopefully I am wrong.
My setup extends 6mm front and 12mm rear, and the fitment is almost perfect all around.

I get what ur saying now, yeah that can be true, but I'm still yet to see the difference Bc I haven't tested them out, so if I feel that the fitment is off in regards to fixing the stance of the car I will def put a spacer out in the back but my arguement for the back is that the 4mm will be enough to even out the front but if not then yeah definilty a spacer is in the works, not really a big deal. But I think it should be minimal as in u won't even notice front in back but that's my guess, I can be totally wrong

Sad news guys I could even get the RPF1's on the front i don't even know if 5-10mm spacers would allow me to get them on the front it seems like the design of the rim, it's hitting the back. I will post the video via my YouTube account.

It appears the center bore of the wheel isn't large enough, which is weird because aftermarket wheels usually have a large center bore to allow you to buy centering rings.

The caliper is hitting way before the wheel is even close to being seated. You can see it right before he cuts off the video.

sorry for the video quality bc it was originally sent to a friend so I didn't take much time. YESS UR CORRECT!! Lol that little issue is costing me 200$ in fees to return the rims haha. Learned big time for this mistake. So the final consensus is ENKEI RPF1's do not clear Big brake kits. They false advertise their products I wish I could speak to their rep's to put them in their place Bc I did all my research. This offset should've worked, everything I had in store for this wheel setup was going to work 275 all around. If anything i would've needed a 2-5mm spacer to barely clear the brake caliper on the front side but this rim was hitting in the wierdest spot, which was telling me that the diameter of the rim itself is too small and henceforth enkei should take that crap out of their advertising that they CLEAR BIG BRAKES pssh. Like u wanna try a setup nobody has but now I know why nobody has this setup and there was no way I was going to run a 20mm spacer lol. But that's my final thoughts on this his whole thread. I hope everyone learns from my mistakes

Also this is some researching I did, since Audi's have pretty much similiar fitment like our cars. Here is some shocking stuff to hear
