Lug conversion
 

I am building my truck with a engine I have, but it needs a cam change with a re-gasket. So I am thinking of doing up the suspension to be a bit more fitting to the new engine. Such as dropping it, and fitting 20's. The engine will be close to 425hp for reference.

I have a C20 with obviously 8 lugs, and my thoughts need to convert it to roughly 5x4.75 to fit the rims I am looking at. The likely rims are BMW 7 Series 20's as they are cheap in my area.

Can I fill, and drill the rotors for 5x4.75 that way I can keep the C20's factory big brakes.

The truck that got me thinking on this trip.

Nope, you may be able to find some spacers though.

You would be better off converting to factory 5x5 and getting some nice aftermarket wheels. You will have a ton of money in having 100% custom wheel adapters made and then still have issues with backspacing. The BMW uses a 5x120 which is 5x4.72 wheel studs must be exact if its only 1 mm off when you torque the nuts it bends the studs and breaks them off. Had a customer with wrong lug pattern wheels couldn't figure why he kept having to replace studs and it was 1mm off on the lug pattern
