Blunttech / Classic Daily S85 V10 E30 M3 Swap

[golde30]

Ahhh, that's the life I want. Custom Badass engine swaps on classic bmw. Gotta get outa CA, I couldnt drive that e30(or even my own e30) on the streets if I wanted to.

I see your doing big things.. literally.. big things...

great to see this is on the move steve / jake

Had a great time ripping into this for a few days. Unfortunately found some rust I was unaware of. Pretty good sized hole in passenger firewall corner. But Jake assures me he can cut it out and patch it. Other than that hole the rest of the car is better than I expected... After working on Jakes new lift I will be ordering my own soon. So nice to have,....

Looking good! Love seeing this unfold.

This.

I am stoked for this project.

They are listed under e82 only, which is odd.

Ah sweet.

Long time no update but moving ahead now. Steve from Blunttech flew in for a couple days to rip it all apart. On to some pictures....

The 135 brakes fit inside the 17" throwing stars. The 135 rotors are a bit to deep tho. Going to have to look for some different rotors.

300mm.de used 314mm rotors. The calipers only allow for a 28mm wide disc however.

I would personally be going with the 345mm CSL discs (for long term supply) with a 13mm spacer, as 17x8" will be perfect.

Example:




Edit: I'm pushing for you guys to do kit because I'm just about to pull the trigger on the 6 piston fronts and twin piston rears and want to run throwing stars :D

I'm interested to see an OE option for big brakes on e30 m3 spindles as well, my car is due for a brake job and OE M3 brakes leave something to be desired...

Does the 135 caliper bolt straight onto the e30 m3 strut? Does it change the offset needed for the rotor?

Saab 9-3 aero cars have a 314x28mm front disc that has a very similar offset to it that may work with a little machining. They are 45.2 mm high compared to the m3's 40mm.

Are running M-systems a must? I found with willwood calipers and my old green m-systems, that I had to run a lot of spacer to clear the spokes. I remember running M-systems with 235/40/17 tires on the front of my old e30 M3 and the offset was already a bit tight. If you have to space the wheel away from the 135 caliper as much as I did with the willwoods, I really don't think it will fit unless you run some stupid 195/25/17 tires. Keep the stretch to butt holes only.

Yes we are finding we need a lower offset rotor than the e46 stuff. The tie rod hits the rotor.
Those saab rotors look good but the bolt pattern is not 5x120... Looks like 5x110


any other ideas?

sub'ed for Blunt's off-color comments.

Redrill or machine the bolt pattern like this guy does for his m3 running Mercedes 300mm rotors.

Thanks Eric Im not opposed to buying new wheels.. I just had these and was trying to run these initially to keep costs down until I really found something unique. But I guess function is most important here I may look at some Apex once we get the rotors dialed in

[blunttech]

Jake has been reading up on rotors for hours. This may be the ticket ..
Corvette Gran Sport rear rotor 340mm diam 49mm overall height
26mm thickness Just need to mill the hub opening. Looks promising and should fit in a 17 in wheel
