FD/FN2/EP3 Wheel Setup Guide

**Stig** · 30-03-2010 11:41 AM

I've noticed that alot of people have asked questions in regarding what wheel and wheel sizes would work and not work on either their FD, EP3 or FN2

I've decided to make a thread in which everyone contributes what wheel sizes they have ran in the past/present/future and suspension setup to help all those who are deciding on wheels.

Here is a template you guys can use

hey will 225 break the rules for running it on the road?
i mean there's regulation saying that we can't go over 10mm than the stock?

anyone knows?

that rule applies to the rolling diameter. the issue applies with the tyre width, profile and the size of the rims ur gonna put on them. there are a few online calculators that will be able to compare ur stock tyres (or the highest measure on the placard) with the new tyres ur getting.

nice work Stig
that helps me a lot, thanks

btw did you test them all yourself?

**Stig** · 30-03-2010 12:08 PM

lol yeah, tested them all myself

**Reclus** · 30-03-2010 12:11 PM

now the only problem for me is which style will fit my needs haha

i'm wondering, whether the suspension for all 3 FD1 models are the same or not

**Stig** · 30-03-2010 12:12 PM

all the same

**Reclus** · 30-03-2010 12:16 PM

great thx

so it wont affect acceleration when I change from 15" - 17" then

**Stig** · 30-03-2010 12:18 PM

if you choose the 17" tyre to have the same diameter as the 15" tyre then you have no problems
