I read your post about your CV boot leaking grease at a track event. I fought this same issue on my 2-11 for a year and a half. I finally developed a piece to hold the boot in place with safety wire and I used Kryton grease (It's hyper-expensive at $300/pound).
If you're still having a problem, let me know and I'll give you details on my fix.
For engine mounts, did you go with the set up recommended in the thread - 60A (front)/85A (rear)?
I've got the track mounts from Sector. The web site doesn't say which "version" they are. They accidently sent me the harder mounts and I found out that only after my teeth were rattling and it wouldn't settle down. I have to say though, the shifter action was *perfect*. But, I sent them back and they sent the version that wasn't as harsh. Much better from a vibration standpoint (hardly noticable, really) but the shifter is now not perfect. I have the LETSLA and it sometimes works well but other times it just doesn't (can't get it out of or into a gear - usually 1st->2nd).
So I'm trying to find the right combination that gives better shifting without my teeth rattling. I track my car but also do want reasonable local driving compromises too.
