Different car but they did basically the same thing for that z3. I got the idea from the $2010 GRM challenge car vorshlag built, where they threw an ls1 in an e30:

Same subframe, just a crossbar welded in to support both ears of the diff and provide some extra rigidity to the rear part of the chassis.

Was worried the extra power would literally rip the diff off the trunk floor, so I basically did the same thing vorshlag did for their car.

Just FYI on the trans bushing failure, I'm sure some of you have brought this to Sikky cause James is aware of the issue and Sikky is redesigning their future trans mounts but they're not ready yet. Here's what they said:

The bushing part itself is glued and semi-captured into a metal bracket. In the past they've dealt with a couple failures where the bushing started to separate. However, Sikky has started to redesign the bushing to a full-captured bushing design, but it's still in the production queue, and has not been tested further than design.

What is the rear end setup?? It looks like a different subframe or possibly a new crossbar to support the diff?

That might be true. I only have my own experiences that I can talk to.

That exhaust tuck is niiiice.

Fair warning. My trans mount failed after a year or two. The design isn't great.

This applies to basically all the mounts that the BMW aftermarket community produces.

[CLM21]

Gotcha. I'll ask them about it.

[shiboujin]

I haven't seen their latest. The main failure point is that the bracket is basically "glued" to the metal mount. So over time, it just separates.

Interesting. Any idea if this has happened with other sikky mounts or if they've redesigned it since the original kits?

Still a few things to be done. Gauges, tuning, fender flares, and debating a cage. Will get fire up videos pretty soon here.
