E46 M3 Subframe Fix Video - JEZEBEL

As most of you Fanatics know, Jezebel is not just any ordinary e46 M3. She was once supercharged. 370kw, 500hp. Using an active autowerke stage 3 supercharger on stock internals.

In 2010 she blew a bearing and an entire engine rebuild took place. Since then, she's also dropped a valve and had to have new pistons and a new Cylinder head installed. The entire Engine was rebuilt with Forged lightweight CP pistons, HPF Rods, ARP studs and head Bolts, balanced crank as well as Vac Motorsports Racing Valves. Its been a long revival process, and the latest drawback to Jezebel's return, has been the infamous e46 Subframe failure. She already has subframe plates installed back in 2010, but they didn't completely stop the problem. Due to the massive amount of power Jezebel was sending to the rear wheels, the subframe started cracking again in other weaker spots that the original repair kit did not strengthen. Another contributing factor to the subframe failing might also be that this e46 M3 sits on Bilstein PSS 10 Coilovers, which are set at their most aggressive and stiffest setting. Clearly after many track days and hard cornering, the inevitable was expected.

In this video, you see how we went the extra mile to ensure no more stress would be put on the subframe, because believe it or not, a new Vortech Supercharger is going back into Jezebel and we are looking for 570hp. She needs to be tough and rigid as hell. A custom designed rear Brace was welded into the car after new plates were also welded in to stop the cracks and repair them. This Brace will now take most of the force thrown at the rear subframe of the e46 M3 chassis.

Special thanks to Leonard at Dent Doctor for helping me with this colossal job, the workers at Dent Doctor for their experience and patience with me, to Burgy from project shift who was constantly helping me get things going and Moranor for the great idea of the rear brace.
