DESCRIPTION

Engineered to work with and match our Multi-Point Front Shock Brace, this Rear Brace is strong and beautiful. Using strong oval honeycomb section aluminum tubing this bar ties the tops of the rear shock towers together for better chassis rigidity.

Installation Instructions: uses factory hardware already in the car, with addition of the four washers that we include with the brace placed between the factory nuts on the shock towers and this brace. Rear shock tower brace has same torque specs as front but requires some minor trim of trunk liner as shown here. Shock tower nuts to 37-43ft-lbs, nuts in the middle span of brace to 12-19 ft-lbs.

Also fits the Fiat 124!

RoadsterSport Rear Shock Tower Brace

Install is quite straightforward but you'll need to cut out a part of the fuel tank shield (which I had professionally done) as well as some of the trim (which was the easiest part).

As for its performance, this coupled with aftermarket sway bars have made my ND2 safer around corners and during spirited driving.

Overall the install isn't very complicated.
It is not a 20 minute install though either if you want it to be nice with no headaches. I would bill 2 hours.

You'll need a 14mm non ratcheting wrench, 14 socket , 15 wrench, 10mm ,8mm Allen, little pry, tin snips and a box knife.

If you take your time and think about it for a little you can cut notches in your carpet to retain the oe look. There's a little of the bar showing under my flat kit but honestly it looks like an intentional shelf. The nuts in the front are hard to get on with anything but a box wrench and be careful as you do not want to snap that stud off. I cut the whole swoopdy off the gas tank flashing and packed the area between the fuel line and bar and fuel shield and bar w foam , no rattles, sweet.

After installing the matching front brace, I became a believer in tower braces! The combination of the two makes my car so rigid and flat around corners that it is almost unworldly how confident I've become. This is paired with upgraded sway bars and coil overs keep in mind but I'm learning how to drive a drift happy car that no longer likes to throw the rear end out as easily. Independent of the handling is the MASSIVE reduction in NVH as a lot of road noise is gone! At highway speeds I can actually keep the radio volume down 10 lower than before thanks to factory rattles and rumbles being tamed. Amazing from a simple and easy upgrade!

Excellent product! Took care of the "happy rear". Installation was a bit time consuming but rather straight forward. Fuel breather required a simple bend to create clearance.

Extremely hard to install. According to the other reviews, it was easy to do, not necessarily so. I tried to send it back and this company would not accept it back, so my wife and I tried our best to install it. It literally took way more than the "20 minutes" it was supposed to take. I took off the four nuts off the tower, the two nuts that go towards the back if the trunk were easier to put back on and to torque, the two nuts that go closer to the seats were extremely hard to take off, and extremely hard to put back on, and impossible to torque. The brace rubs against the fuel line, Good-Win says it is no big deal, it is a big deal to me. I complained about not being able to replace the gas line metal protector, I was told to cut it to fit and cut the carpet to fit. We will try that maybe on the weekend. As of right now, my wife hates the look, she hates the design. But since we cannot return it, she says she will have to live with it.
So, beware, if this car is your wife's daily driver, make absolutely certain she will be ok with. Right now, mine is not.

The quality on this brace is apparent the moment you open the box. My trunk was already stripped of interior panels, but taking that into account it was no longer than 20 minutes for install. It stiffens up the rear of the chassis quite well, making the car more predictable as you start to lean on it harder. It also ties into the trunk floor for that extra bit of rigidity, and the two piece design works nicely to tuck it under the fuel filler pipe.

Received my RoadsterSport rear strut tower brace yesterday and installed it today. I'm impressed with how well-made it is. Surprised that Goodwin doesn't have a good pic of the brace showing that it is solid welded on the passenger side and requires only one bolt on the driver's side to attach the bar to the shock tower brace. (this would be so much easier to explain with a picture). Anyway, this bar, welded on one end and with it's added attachment to the trunk floor seems much better engineered and therefore stiffer than the options that run the bar higher for clearance over the fuel tank filler pipe.

Note to autocrossers running Street Touring and Street Prepared: this is an added 3-point strut bar and might not be allowed at tech inspection, bumping you all the way to Prepared class which seems unconscionable. I don't care with my car, as its being built to be a grand-tourer and canyon carver.

Installation was a breeze, even for this 76 y.o. grandmother. I trimmed the fuel filler shield with a skill saw and a 17 ppi fine tooth blade. Hardest part of the install was trimming the trunk trim pieces to fit around the brace.

This is a good time to install sound deadening material to the trunk sheet metal AND the fuel filler guard if you haven't already done so.

FYI You will find one of the five sheet metal brace's attaching bolts would need to be installed under the brace. I cut that bolt down enough to just fit under the brace and found it was then too short to engage the threads. I later found that it would have interfered anyway with slipping the trunk trim under the brace. So don't worry about that fifth bolt.

To be honest, this bar was a second choice to an out-of-stock first choice, I got this and the Cobalt front brace at the same time. In hindsight, though, I like how this ties to the floorboard and I'm very happy with the performance. This car is not a daily, mostly SCCA Time Trial and TNiA events and the occasional back-road sortie. It is not at all intrusive on the trunk's usability, and after trimming hard plastic for the roll bar trimming the trunk's fabric liner was a breeze. I've got a long list of items purchased from Good-Win, and in every case I have been extremely happy with the results. This off-season the list will get even longer.. I don't see me shopping anywhere else.
