It all depens if you are going to run oil shocks 50746 or the friction shocks!

If you run the friction shocks then spring kit 53333 should do the trick if you put a 5mm spacer ( fuel hose) like tony says on rc-mini.net. If you are going to use the super mini oil shocks then get the short spring: 56630-56631-56632.

Please refer to posts #8176-8177-8181 wich aren't that far back.

Hope this will help you, I've been through this step already and this is what the guys sugested.

Don't forget about the ride height it is VERY IMPORTANT!

Have fun
