Active Autowerke Differential Support Bracket

[m3f_Jmannumber7]

Trust me, more than a metal plate. Very clean looking, and you can barely tell its there. $265 will seem well worth it when you are trying to limp home from the track, which is a pain, not to mention the lost seat time and $$$ from having to cut your track day short....ask me how I know



If you really need convincing I'll try and get under that car and snap some pics for you. LMK



Pictures would definitely be nice as I haven't seen any pictures of it in use before. If you can't get around to it, by all means don't worry about it though :thumbsup2:

Under $100 for a $35 Mike Radowski brace with $60 worth of welding (less if you pull the diff and take it to a welder like I did to have it done for $30) is even better. Proven on 700 rwhp drag cars.

here's another satisfied customer with the AA DSB. numerous launches/track days and my car isn't exactly driven lightly otherwise and i've never had a diff bolt break.

I'm not understanding how that stops the bolt from breaking. Is it the movement from the bushing that causes it to break? And this holds it in place so it can't flex with the bushing?

[m3f_Richardspe_ff9fba485e]

Yep. With the addition of any dsb, you take the front mounting bolt out of single sheer and into double sheer. In other words, you are supporting the bolt at 2 points, making it much harder to break.
