Rear wilwoods - confused!

[BertBert]

My clubsport has solid rear disks and wilwood 4 pot calipers. I have bought new ones using Rob's part numbers (120-5093), but on coming to fit them they are for thicker disks (1&quot. Looking at the rally design web site, it looks like 120-5003 are right, but they say they are for 9.7mm disks and a quick measure of the disks shows them to be 10mm. Also the mount offset on the website is shown to be 19.7mm. Measuring the hub, my mount offset should be about 14mm.

Anyone shed any light on this?

Thanks

PS I can't look at the old ones as they have moved on!

The offset could be reduced with spacers if needed. One question is do the calipers bolt to the upright ok? My 2-pots the distance between the lug mounting points is a lot shorter than the 4-pots? or have you bought ProSport uprights?

[BertBert]

The uprights are unchanged, I was just trying to replace the calipers. The offset is too small so can't be sorted with spacers. I could just get ventilated disks (same as the front), that might be easiest as I can check taht the fronts fit the rear.

I am not sure if it is a standard Radical clubsport setup or not.

[BertBert]

yep, just checked that the front ventilated disks (mk IV fd escort) will sort out the rear. Off to halfrauds then!

Interesting, always thought the 2-pots had a smaller distance between the mounting lugs compared to the 4 pots ... learn something new every day

[BertBert]

ahhh, just to confirm, the car had 4 pots on the back but with solid rear disks. Does that mean it has prosport rear uprights?

Does the prosport have solid or vented rear disks?

[RobC]

Ah, that makes sense now...yeah they are Prosport uprights

Hi Simon, what have you got? Calipers or disks?
