Hello I own a SR3 earlier models. on the front I assume they converted to 280 mm discs. But now the bells are damaged and the discs are mooving too much.

What is the tolerance of "jeu" ? i can insert a 1.3 mm gauge to stop the disc mooving.

disques sr3 2
disque sr3 3

3 solutions:

-find   a pair of bells but Im not sure its a radical disc I have ?

-retrofit to standard 280mm discs but do I need floating calipers ? and witch disc (from usual car) use 280mm discs that would fit ?

-buy new discs and bells and sale my wife's car to pay ! 🤣 

thanks for helping me  !

Hi Nicolas... Unfortunately the discs (and bells) fitted to your car are no longer available as far as I know. I searched for these a while back for a customer of ours but nowhere to be found. The quickest and most straightforward solution is to upgrade to new style SR3 RS 280 mm floating discs but I'm pretty sure you will have to replace the calipers too... Also check if the new calipers will fit to the upright though I think this should be OK.

All the parts you'd need are here:

It will be a costly upgrade but you will then be safe with replacement parts for a while to come as this configuration is still used on new SR3's.

Hi Thanks for searching for me !

I finally found another solution. Keep this 280mm discs , Cleaned the bells where they are damaged and made 20 oversized T slot like that we no longer have excess of space .
