Hello ladies and gents! I DD my AP1 and will be using my stock 16 inch wheels for winter tires.

For the other 3 seasons I want to setup the car with Enkei RPF1s. I've read through the entire RPF1 thead here on S2ki and I think I should be ok with this setup, but I want to confirm with you all before I take the plunge. I am currently on a 0.75 inch drop in front and 0.5 inch drop in the rear (I have 2 finger gaps clearance all around on the stock 16s).

Front: 17x7.5 with 48 mm offset and 215/45/17 tires

Rear: 17X9 with 45 mm offset and 245/40/17 tires

I don't want to relocated any tabs or roll the fenders, this is my main issue. I can also run 17x8 in the rear and fit 245/40/17 if this will be necessary.

Thanks in advance for any advice/comments!

 

You will need to roll the fenders with those. If you don't want to roll the fenders you should look at the PF01SS in 17x8 +50 for the front and 17x9 +60 for the rear. I will still cation you that since you are lowered the fronts will likely still rub and have the chance of causing damage due to you being lowered.

I would look for different wheels if u do not want to roll your fenders.

 

Wow I didn't realize that it was so bad with rpf1 at 7.5 inch width in the front. What is it about the wheel construction that makes it more prone to rub than similarly sized oem Ap2 wheels? Both the rpf1 and the oem ap2 wheels are 17. Thanks again for the advice!

 

Offset. It will be very close to not rubbing at that height if you run max negative camber. You really are on the edge of what will fit without fender mods. The 8" +45 won't give you any more clearance in the rear compared to 9" +45 (assuming same tire size) and the 9" looks so much better.

 

OFFSET. The wheel is .5 inches wider and sits 13.4mm further out. Further the front wheels turn (shocking information I know) and when they are turned and the suspension is compressed guess what is in the tire's way when it is moving? The fender. At OEM height it may not play a factor or only would in the move extreme cases but you have lowered it moving the fender closer to the tire. Now the suspension has to compress less before the tire grabs the fender. Also now that I punched int he PF01SS specs that sticks out more. Solution roll the fenders because it is much better to roll them then it is to have to fix the damage caused but a wheel grabbing the fender lip.



For learning.

Thanks very much for the information. Been playing around with the online tool you linked, and it's a great resource.

It seems that the 17x8 50 mm offset PF01 will stick out further towards the fender than the 17x7.5 48 mm offset RPF1s. So it would seem to me that I have a higher chance of rubbing with the 17x8 PF01 than the 17x7.5 RPF1s.

If I don't want to roll the fender, it seems I must stay with stock AP2 wheels for 17 inch. Is that an accurate statement?

 

TRM wheels on tire rack +63 offset, could use those as well

 

Just saw those. The look is very similar to the oem AP2 wheels, thanks for the heads up.

Spoon makes the cr93 wheels which may work, looks like the offsets are in the 55 ish range for those.

I went back and took a look at comparing my AP1 setup (16x6.5 55 mm offset 205/55/16 tires) with the RPF1 (17x7.5 48 mm offset 215/45/17) and the difference to the fender is 19.7 mm.

"Compared to your existing wheel, this new wheel will have an inner rim which is 5.7mm closer to the suspension strut. The outer rim will poke out 19.7mm more than before."

 

Keep in mind the ap1 has more margin of outer clearance to play with over the ap2. Both cars run the same offset front and rear, but the ap1 has .5" less wheel up front and 1" less in the rear. Thats 6mm more sunk in up front and 12mm in the rear. Back in the day I ran a 25mm spacer all the way around with factory wheels to remove some of that gap, and no rolling was needed yet. Another 5mm and it would have.

Up front the issue becomes steering clearance and driving habits. Its smart to at least roll the front to prevent damage, even if it looks to clear with the wheels strait. But yeah technically the 7.5" +48 would fit fine up front, all the way up until it doesn't. The 9 +45 with 245 would fit in rear without rolling with some additional negative camber, about -2.5. 255 would be an issue.

assuming you would be rolling the fenders anyway, you might as well up size the front to the more comon 8+45 to better mate to the rear 9+45. Roll all the fenders and run the typical upsize of 225/255. But stock 215/245 on this set would be fine as well.
