Thought I'd start a definitive thread on reinforcing the rear subframe. And get a conversation going. First off, is it even neccessary? There's no point in wasting your time and adding weight.

Mazworks makes a reinforcement plate that welds betweein the rear diff mounts for the s14, supposedly they had a cracking problem in that area on their drag car. Looking at DSGs 240maxi it looks like the only custom work was a roll bar attachment point. Autech makes a crazy bolt on tubular brace.

I don't want this to turn into a S13 vs. s14/s15 sufbrame thread, so I'll outline the difference as I know them for the noobs: the s13 subframe has slightly more anti-squat built into the control arm mounting points, the s13 has provisions for 4 solid mounts at the rear of the differential cover vs. the s14/s15s rubber mounted 2 points, also the chassis mounting locations are slightly different requiring offset bushings if you want to update a car with an s13 subframe.

I just ordered a set of SPL solid diff mounts because they were the only ones I could find that included the rear diff cover mounts for the s14. I seriously believe that the best way to strengthen your subframe is to solid mount EVERYTHING. This effectively turns your chassis and differential into subframe reinforcements.

Here's all the pics I've collected over the year. Stolen from all over.

GSRacer?




Autech



DSG




Nissan Road Race Forum I think?




Good Idea? Bad Idea? What have you done? Post some pics!
