How is this subframe crack?

[01SG]

Thanks for the suggestions, I'll be sure to check those places out. I saw the CMP bushings were for lowered cars, so I might just go OE or Turner's. I wanted to order it all from one place, but since that's out I'll look at the Vincebar too. His kit also has the gussets to accomplish both front and rear reinforcement on top. I'm going to find a shop with experience and see if they have a preference; it appears they will both do the job.

I cleaned things up a bit and poked around some more after dropping the diff. I found another crack, predictably around the front right subframe bushing, in between that and the gas tank.

I'm thinking about buying the whole CMP kit; I want to do this once and forget about it. So that's the underside reinforcements, the topside bar, plus the extension for the two front mounts. I understand their solid bushings are tolerable for a street fun/weekend car as well?

I was considering Rogue. I'll definitely give them a call, among others. I'm willing to travel to a place that has lots of experience for this; I hate to take my car to a shop for any little thing..

Once the differential is out I'll get more pictures, so far there's no other cracks. I suppose it's par for the course, time for winter hibernation anyway, and come spring every bit of the suspension will have been replaced and the floor reinforced.

CMP is very arguably the best-engineered permanent solution. However, I didn't want to lose boot space so went with stealth bar. Its relatively easy to make one. One of my mates welded it up for me.

I have a convertible, so only needed rear top reinforcement, but coupes apparently need front and rear RACP reinforcement on top. CMP is the only one that offers both to my knowledge.

And yes, with new bushings it stiffens up the backend nicely...

I live in Stamford, CT used to live in NYC and have always taken my car to TKX in Long Island...they've done my subframe reinforcement, Vanos, Rod Bearings etc. It's bit of a drive from where I live now but they are very familiar with our platform. I've heard good things about Hi-Speed Motorsports as well, but never used them myself... they're in Milford CT

+1 for HSM. Never used them personally but seem to know what they're doing in the interactions i've had with them.

I have the entire CMP kit in my car; plates, topside bar, front mount extension, 6 point brace, solid raising subframe bushings.

Rear end is going nowhere lol. As for the solid subframe bushings, you hear the faintest of diff whine, but this isn't really heard over my exhaust (it's pretty loud). I've stayed with OE diff mounts.

I felt an immediate difference once all was in and aligned. Car almost felt a bit twitchy in the rear as it's so tight now. Front end feels comparatively loose imho.

Yikes. Not familiar with your area but Rogue Engineering in NJ comes to mind.

Damn. Make sure it's repaired properly (i.e. stop-drilled and welded etc etc). Also make sure you reinforce the racp from above and brace it correctly. Remember, plates don't fix the issue.

Found this while dropping the differential today. Can anyone recommend a good shop in the New York area?
