  1. Well thanks Chris. the car is truely amazing for something that has single point pivot trailing arms at the rear..

    And I have removed the Summit Rd video, it was really a demonstration back when I had just got the car going again after the upgrades, and the actual Summit Rd was covered in gravel, quite a boring video imho. A new video will be made this summer sometime, with hot tarmac and R comp tires...

    Couple of videos here:

    and

    Waaaay too fun.


  2. Looks like the vibrations from the Delrin caused the 4 bolts holding the mounting arms to the block to back out and cause the crack

    tc, Wasn't directly the mounts. The bolts backed out and the resulting gap between the arm and block caused the cracks. Solid engine mounts are still very worth it. Just have to locktite some key bolts, better than spring washers really. I'm happy to be the test dummy for Bimmersport.

    New mount will get here tomorrow for 15 dollars inc courier thanks to Jono51 from Welly :)

    Pros for Solid mounts are: Easier to change gears as the box doesn't roll with the engine and cause misalignment with your muscle memory, Much crisper 'launches' and shifts between gears, motor doesn't waste torque on twisting the engine on the softer mounts. Dash board vibrations are full raze.

    Cons: Oil cooler lines fall out of block and bolts holding on engine mount arm. And resonant frequency of the dashboard is sometimes hard to talk over hahaha


  3. You are impossible to comprehend.

    Looking underneath my standard-ly lowered e30, the control arms are on a 20 degree approx downward angle. I don't understand where you got 0.2mm of movement from to get .008 degrees of camber change from what we were talking about? But if you were to lower the car more, even from a already nicely lowered height, the camber would increase quite noticeibly. And that's all we were talking about before.. The Camber gains when lowered, but you lose the amount of travel you have where you still gain camber.

    And everything I have read about racecar setup has Toe Out on the front wheels, google 'racing alignment settings' and just the first page has some great info, I bet actual books written by race engineers would have the same thing.

    Here's a whole page of real people using Toe Out on BMWs http://www.e30tech.com/forum/search.php?searchid=2292028 Making their MacPherson strut cars handle amazingly.
