Just purchased a set of rpf1s for my Evo 9 what size spacers will I need for the front?! Size 18x10 +38

 

20mm spacers for the front.... id also recommend 5mm for the rear as this wheel doesnt clear the trailing arm in the rear

 

Anyone have pics of this setup? Thank you for your help bro. Just wondering how far they will stick out if I do that 20mm spacer.. Or is there a different brake kit I could go with so I don't have to use spacers

 

just search, youll find what youre looking for. they wont poke out much in the front, +18 offset is perfectly fine for the front.
i wouldnt suggest swapping out your brake kit, but rather getting wheels with a better fitting offset. 18x9.5 +15 rpf1s dont require a spacer but youll need a roll and pull to fit them in the rear

 

this i run the exact same setup with a 285/35-18 hoosier and they fit. without the 5mm rear spacer it rubs the trailing arm.

 

Awesome thanks for your help guys I appreciate it I'll post pics and let you guys know how mine turned out

 

I am also running the same setup. 18mm Spacer up front and a 6mm in the rear. I did roll and pull the rears and run a fender mod on the front to be safe.

 

Where are you getting your spacers? Can you post better picture of your fender manipulation? Do you need crazy spring rates to control the grip?

 

My front spacers are slide on hub centric from JMfab. The rears are slide on from Ciro Design. I am running 11k front and 12k rears. The fender mod is pretty simple you just put a piece of metal where your fender meets the chassis to space it.

 

The front fender mod isn't necessary in my opinion. Otherwise, the advice is dead on for running this setup!

 

Get quality spacers! I would recommend getting extended studs in the rear.

Why is it that those 18x10 +38 wheels with 20mm spacers at front seem to fit so well, but 18x10 +18 such as xd9's have a lot of poke? It should be the same, shouldn't it?

 

aggressive camber most ppl running the RPF1s are tracking and, like me, have at least 3* of camber in the front, which might be the reason they fit better
