Absolutely!
Being unsprung and rotating, brake weight is very important

For example, having a 30mm thick rear rotor on an E30 is just carrying around weight you don't need.

Yeah, there wasn’t another option unfortunately.

I’ll weight these soon. If anyone has e30 325i late model calipers with carriers and rotors they can weight that would be great.

I can do this. Theyre not late model (1988 iirc) but I can get a number up in the next few days

[paynemw]

can't wait to see these MASSIVE wheels and brakes on the car!

[Jean]

Ok so here are the weights :

- wilwood 4 piston bare caliper - 5.1lb
- wilwood 4 piston caliper with front/ rear massive brakes caliper bracket - 5.6 / 6.1 lb
- hawk 300x32 rotor with front massive brakes hat 10lb
- hawk 300x32 rotor with rear massive brakes hat and ebrake hardware 11.5lb

So, haven't updated this thread in a while. Brakes still waiting to be installed LOL

Wheels I waited for over a year finally went into production, so now I have a set of 15x10s and 15x9s.

TRM 15x8s went to a new home, switched to an intermediate setup for now, 15x9 with 245/40 RS4 street tires.

My intake boot developed a leak, no wonder throttle response was funky, so I am ordering a new one from BMW to get that fixed.

Spare early fuel pump housing needs to be prepped with a new pump, so I can get cavitation and long starts to go away.

Other than that, haven't really driven the car more than maybe 1000 miles last year.

Here are so new pics of the current temp wheel/tire setup.

When you say throttle response was funky how do you mean? I have a problem with mine stumbling when cracking it open from fully closed.

[Jean]

It had hiccup , and would want to die coming to a dead stop. New intake boot fixed it for good.

Looking good, I’m excited wide 15s can be made.

Needs more action shots putting those 245s to use!

Brake time?

[Jean]

Finally Massive Brakes 300x32 kit has been installed front and rear. I can now confirm these clear both, the Sparco FF-1 15x8s and Jongbloed 15x9 wheels (I imagine the 15x10 will clear as well, if it's same barrel).

Currently dealing with issues bleeding the wilwood dual master setup, I can't get a solid pedal bleeding the system using the old school pump pump pump hold bleed method starting from RR going to LR to FR to FL calipers. I also tried using vacuum method, didn't work any better. Combination of pump/hold/bleed AND pressure bleeder worked somewhat but pedal is still not solid .

Going to try and bleed one side of the car at the same time (AKA 3 man bleed) how Tilton suggests it's to be done. If this doesn't work I guess I'll have to remove the stupid pedalbox, adjust the balance bar all the way to the front, bleed the front, then adjust the balance bar to the rear and bleed the rear. Absolute nightmare of the setup.

She is back on the road , installed my Sparco FF1 wheels , these are freaking light ! With Toyo Proxes r888r 225/50 tires these are lighter than my previous TRM wheels .

Jongbloed 15x9 with 245/40 are off the car for now .

Both sets clear these brakes, so that’s good 😊

MT1 side skirts and some interior upgrades are next .

I was talking to Jean on FB about this already, but I found out that Tirerack does carry the 15x9 Sparco FF1, but only lists it under miata fitment (MY1999 works).
ET is a little low at 35, but better than too low IMO. I think they're ~1lb heavier according to TR.

I'm trying to decide between the 8" and 9" versions, just not sure how the 8" would handle a 245 in something like an RT660 or RS4, or if it's worth even thinking about 245s with such slim pickings for tires.


Re: Bleeding the Massive delete:
I remember bleeding the Tilton dual master brake system from dry/near dry was always a massive pain on my FSAE car, usually required multiple attempts to do it over the course of a few days. A pressure bleeder probably would've helped.

Hell, even when I rebuilt the master cylinder and replaced the front lines on my motorcycle, it took me a few hours until I gave up and back-fed the system from the caliper with a giant syringe.
I think it's just how it goes.
