As title.
After the troubles I had trying to fit 15 mm I went for it with 20mm.
However,anyone else think its a bit much on the rear with standard alloys?
They're flush with the body and slightly shielded by the plastic spats but I'm not sure if 15mm would be more subtle. I still have the 15 but would need to do a few mods to use em.
Oh also fitted a new spoiler

 

I hope you won't sandblast the paint on the side of the car.
How is road behavior affected by the spacers?

 

Good point regarding paint!!
I've not been far yet but everything seems fine. From past experience I would say the steering feels a bit slower with spacers.
It's hard to separate real changes from imagined ones. A blind test would be better but of course impossible when you mod your own car.

 

How come you had a problem to install the 15mm , I have just installed them with 20" sentas and lowerd HR springs with no problems The only thing I had to do was cut off the non threaded ends on the studs,.

 

Don't know what the situation is with other sentas but mine foul on the nuts that hold the 15mm spacers on. It's only a couple of mm but I would have to grind the wheel a bit.

 

Instead of grinding the wheel, sherbercars was saying that you cut off a bit (the non-threaded part) of the OEM stud.

 

Correct. If you look at the back of the wheel after you mounted & dis mounted you will see where the ends of the studs ( bolts ) that hold the spacer on, have scored the inside of the wheel , just cut off the end of the stud , it is just there to help guide the wheel on into place .

 

You misunderstand guys. Mine don't foul on the studs but actually the nuts. Weird I know but it's the case!
