Having murders, i have tried fitting my Renault 21 2.0l txi discs to my r5 gt turbo.
I bought some willwood 4 pots and had bracket/extenders made from andy tnt.
I thought at fist i was putting them on back to front or something because the calliper would not line up with the disk.
So i fitted the gt turbo disks back on with the extenders and the callipers all is well, what is happening when the 285 txi disk is sitting on the hub the disc has a larger offset ie the disk sticks further out therefore not being able to get the disk to fit where its supposed to. Its about 7-8 ml out.
I rang brembo and asked them, hard work female
, im going to ring back tomorrow.
can anyone shed some light, loads of people have fitted larger 285 disks and just used r21 txi disks with extenders
