03 G35 Sedan, 6MT: Stillen Cat back exhaust / This does not fit. Unit feels of good quality and construction. This does not fit if you have the Stillen cat back exhaust. Aside from that, I would recommend this product for purchase.

2004 G35X Sedan Let me start with one thing, the packaging was great, everything that was listed came with it. The hardware was quality and the brace itself was an impressive work of art. This will fit your G35 Sedan, and especially if it is AWD! You just need to hammer in the spare tire well. Surpris, this did wonders for my driving experience, stiffer rear-end, less body roll, more comfortable ride, less road/mechanical noise, and I genuinely feel like I get up to speed faster.

07 G35 coupe 6MT, I purchased this brace because I kept having the dreaded differential thud when shifting too hard. This brace has tightened the rear end significantly and the car drives so much better. Also, this brace clears the HKS true dual exhaust. Can't go wrong with the price/benefit ratio, I highly recommend it.

I'm not sure if I got a dud or if quality control is bad. The brace I got was slightly warped out of the box, Spent like 40 minutes trying to see why the screws wouldn't align. That's when I placed the brace flat on the floor and it was slightly bent. I had to hammer it a little to get it flat and it finally sat flush on the diff, the screw holes lined up perfectly. I would give 2 stars but this product is actually pretty good, car feels nice and planted.

this bolted up to the diff housing just fine but I don't care for the design of this brace because the drain and refill bolts are blocked by the brace. in contrast, the Z1 brace does not interfere. I think they could have done a better job designing this to not get in the way. in order to drain the diff, you have to remove this brace which is an unnecessary nuisance. but if you don't do that often, then it's no problem.
