The Turner front subframe reinforcement kit is $34.95 and well worth it. Since you will be in there anyway, it will be a snap to take out and do the work.

Some subframes already have a factory "guesset?" reinforcement on the bottom side. It prevents you from welding on the triangle pieces that come with the kit to that side of the frame, but it seems like a beefy enough modification that should hold. You will still be able to weld on the top portion regardless. See pic below:

Luckily, I didn't have any cracks or signs of stress but I do sleep better at night knowing the car has all of its weak points reinforced.

Here are the front swaybar link reinforcements on the front struts (primed just after welding)Notice the Ground Control spring perch collars in place. This kit is only $14.95 from Turner.

If you're doing a rear swaybar anytime soon, do yourself a favor and get the Ireland Engineering kit. It is %1000 easier to install then the Turner kit and it is less expensive boot.

A local shop fabricated custom reinforcements for the rear sway bar endlink attachment to the a-arm:

Don't even think about attaching a beefier bar without reinforcing this point - it is very flimsy and will tear out in no time.


Grassroots Motorsports magazine used UUC's new tranny mounts and reinforcement on their project E30 M3 and they love them. The price is right and you don't have to do any drilling :^) ($70 for the kit)

Eurasian has a good price on their engine mounts - I paid $138 for the pair.

Alles Beste!
