Im upgrading the drivetrain on a car shortly, but I cant really find any suppliers of things like bearings, rosejoints, driveshafts, gearboxes, hubs and such...
I regularly use demontweeks, but theyre not really coming up with the goods this time, and I know of a few other larger places.
Does anyone know of decent suppliers?

cheers!

That really depends on the type of car and the parts you want. What is it you're upgrading and how far do you want to go? Lots of parts are interchangable between car models from the same manufacturer.

My Toyota MR2 mk1 now has Celica GT4x4 front brakes and MR2 mk2 turbo rear brakes. It'll gain a Camry 3L v6 engine and a MR2 Turbo gearbox / driveshafts this winter. Great upgrade with double the power and torque but without breaking the bank on full race spec parts from DT

mcgill motorsports for the rosejoints

or for the ordinary stuff I'd just go to pentland or digbro

rally design for gearbox parts if a type nine

snazzy, thanks! its an old tvr based on grenada. thing is im changing it so much it doesnt really need to match up with whats on it currently.
Cheers again
