If all you want to do is convert to a 5 bolt set up would it not be possible to get a machine shop to weld some plugs into the 4 bolt lug holes and then redrill and tap in the desired 5 bolt pattern? This should work and properly aligned the new lug holes should be able to have at least 4 of the holes tapped into "virgin" steel and only the 5th possibly partially into the plugged area. Just offering an alternative idea... there's more than one way to skin a cat...

No, no, noooo... not enough material available. I have heard of one person back in the day doing something like this, but keeping their bolt circle at 100mm... Not much of an upgrade to have a 5x100 bolt pattern, and it's rather hack to do all this IMO.

OK I've never looked that closely at it... IK that is a mod some off roaders use to fit different wheels to some hubs...

Bumping this with a whole other kettle of fish.

For the rear, given that the late model E30 bearings are the same size as the E30 M3, E36 non-ti ones, E46 323, 325 and 328 or Z4 non-m, should it be possible to install an z4 2.5 hub or E30 M3 hub, e46 328 rotor and E36 m3 caliper on a stock E30/E36ti trailing arm, given an adapter for the caliper mount?

This 300mm.de reference seems to indicate it is, hence their offering of the adapter.

The reason I'd like to go this route is to match my E36 m3 front brakes as close as possible.

Im a bit confused can a 5x120 bolt patern hub fit in a e30? has anyone done this. I have a 91 e30 and i just bough adapters and my style 5 2 peace are running a little wide by like a 1/4 inch - 1/2 inch.

Yes, you can fit E30 M3 hubs with regular bearings, or any E36 non-M hubs (but the axles won't match up, I think). The issue lies in installing brakes.

so can you not just use e30 rotters and re drill them?

No, the hub bore isn't the same (57mm for E30, 72.5 for E30M3). If you're going to convert, it makes the most sense to simply get M3 calipers (same as E32 735i) and rotors along with M3 hubs--it'll all bolt right up. M3 rotors aren't that expensive, and it's definitely better than drilling and boreing a rotor.

I'm personally trying to find a way to run the M3 hub, E32 caliper and E32 rotor (which is bigger than the M3 one) on the E30 subframe.

So how much is it to go to the e30 m3 hub set up? say if your buying it new from eeuroparts or pelican. say you buy all the parts rotors hubs and brake assembly for fount and back. Would you still need to do custom fabrication?

Its just a bit confusing when I read though and I see people saying one thing and then another thing.

You can get e30m3 hubs new from ecs for $130US, or i've heard Timken makes them for about $130 canadian which you can pick up at any parts store.

The question of going custom is a subjective one. The simple way is also the most expensive: e30 m3 all around. Cost would be at leats $2000

The next-simplest way is to get the e46 330i front 325i rear adapers that max399 sells on r3vlimited, total cost around $1200.

The e36m3 front/e36ti rear is probably the cheapest, but I believe it to be unbalanced.

Thus, i'm trying something way out of left field, e36 m3 front assemblies and hybrid rears. I've settled on z4 hubs and i'm designing a custom adapter to run e36m3 rotors and calipers. It'll keep the best balance, and actually end up pretty cheap ($1000 all told).

Pm me your email if you like, i can send you my parts lists and brake bias worksheet.

Yes, he lays it out quite well. My rear option is closest to his third option, mz3 rear arms. Mine will be a third of the cost, however.

So I emailed Timken about the hubs and well see what they say. But I'm on eeuroparts and oem e30 m3 hubs are like 250$ each. I go to the z3 and there 50-100 non are oem though. they all look really close but hard to say because theres no specs. Where do you get the specs for these hubs other then measuring?

I guess they're no longer on sale

If you go Z3, make sure you get the 1.9L ones, otherwise the offset will be far too high. (around 52). Z4 2.5 is a better bet. To be honest, though, on a piece of cast metal, OEM is not the be-all and end-all. I'm going with some aftermarket Febi hubs for about 50 euros each.
