Colorado general chat...

So I mounted up my RGR's. The 215/45's were quite a bit larger than the tire calculator I used specified they would be. I'm thinking it's a difference in tire manufactuers??? Not sure. It looks OG like I'm riding on 20's!

I need spacers, at least 10 prop 15mm. Anyone know a place to get them and longer lug bolts locally?

I also need my caster adjusted. When I got my alignment the idot at Brakes Plus had no clue how to do this. Do you guys know? I was going to take to Autosporwerks or Bimmerhaus for a proper alignment.

If my car needed more low before it really needs it now!

I don't think caster is adjustable without camber plates. Add Tire Source and SCR to your list.

[blefevre]

Yeah, no caster adjust. Your CA bushings could just be way shot causing the caster to get off.

Well shit. Still got air in the system. Back to bleeding.

[Bimmerman325i]

Just so you know Roland, I tried bleeding my E30 with a pressure bleeder once and it never worked. I bled it (after it didn't have rubber brake lines for a week) with the tried and true pedal method in half an hour, and BAM perfect pedal feel.

Hmmmmm..... I have a few other tricks up my sleeve, but I will try that if that if it comes down to it.

Sometimes the rear brake caliper bleeders aren't the highest point in the caliper, and you have to take them loose from the car and reorient them to get the air out.

Also, I've had equal luck with pressure bleeders and pedal bleeding - Never had one work without the other.

Pulled the head off my M3 today... Turns out, when you relentlessly abuse something for as long as I have, it wears out. Shocker there.

Lots of oil being burned in the combustion chambers, due to blowby as well as valve guides/seals. Lots of deposits in the exhaust ports. Cylinder walls have no crosshatch at all on the thrust-bearing sides of the pistons (where the skirts ride.)

I installed new CAB bushings in NOV. Something is up because my front wheels are way forward in the wheel wells. Even with spacers I'm gonna rub the front wheel plastic. Bimmerman are those places local?

Also the rear RGR's won't fit on the hub. The little metal rings inside the wheel stop about 1/8" on the hub. Could this be an ix to I thing? I doubt it. I didn't have time to clean and grease the hubs either.

So what's the diagnosis? Engine rebuildable or just time to replace?

Tire Source is in Boulder where the old Ford dealership was, and SCR is in Loveland and is where Chris works at. Both are great places.

...So does this mean you will be selling your S50 to me for cheap?? ;)

Also, Cloudbase, i believe the iX and i have the same hub diameter. Just wire brush both mating surfaces and use a little brake caliper grease.

I'm going to swap in a lower mileage short block and rebuild my current head. It's the cheapest way I can get the car back to 100% (or close to it.)

Sam: Not going to have anything leftover. The shop is going to rebuild my old block into a pretty hot motor for one of our racecars.

Also: front control arm bushings are pretty much the only way to adjust caster in a BMW outside of camber plates. Did you install offset CAB's instead of centered? That will change it. Also - As long as caster is even from side-to-side, it doesn't matter if it is out of spec (at least as long as it is on the high side.) Too little caster causes problems, too much rarely does... within reason.

[Cloudbase]

I'm happy to give Chris's place a little business. I'll drop SCR a line on Monday.

I did install offset CAB's I'll have to see what the rubbing is like with spacers. Might have to back to centered to make my OG's work!

[blefevre]

Yeah, the M3 offset ones will do it. I barely rub the front plastic fender well with 225/50/15. The offset bushings are really nice, keep them if you can.

Yeah, I've got most of the air out. Now I'm just not sure if the pedal is soft, or its just in my head.

Awesome(ish).

Turns out it was just in my head. phew.
