e30 are 22mm thick for the vented discs.

You have to machine out the centre bore of the disc ,then they fit behind the hub like the datsun discs , you have to drill new locating bolt holes ,but its all easy to do . e30 discs come in vented or solids.

Iam using BMW e30 260mm vented discs with Wilwood 4 Spot Dynalite calipers and hawk Pads , this all Just fits inside a 13" rim ,i made up a dogbone bracket to fit to the jap 180b struts. This gives you the Lightest and the largest rotor with 4spot you can fit inside a 13" rim , Bmw rotors are around $170 a pair . Wilwood 4 spots are $230 each new and hawk pads $150 plus your dogbone bracket , Considering all parts are new ,its not a Bad deal for what you end up with .also using a wilwood adjustable brake bias valve
*all prices are Aust $$

If you can make over ( fly wheel ) 100HP Per litre in Na 2 valve motor your doing well . So this means if you have a 1.5ltr x100 = 150hp at the flywheel

910 or 510 ?
