Hi guy's
Didn't had much time to work at my roadster, but last weekend i did.
Found out that i made the rear lower wishbones to short

.
Ordered new ones at 3GE, put them one, rebuild the back, adjust the ratchet like you told me, and no mre problems with my drums !
Result after last weekend: my roadster is on wheels !!! Jiehaa !
Now struggling with my engine mounts, but for now, i'm a verry happy man.
Pictures will follow next weekend.
Thank you all !!!
Wim.
