DRCUSTOMPARTS strut braces and mounting brackets really help the W-body cars handle the corners so much better. www.drcustomparts.com

Customer feedback:

Received your front and rear brackets for my grand prix. Had more trouble opening the package than putting in the front and rear bars. Cant tell you how happy I am with this upgrade. Quality product and best bang for the buck.

I put the Strut Tower Bars on and wow what a difference. Right after I put them on I took the car for a drive and the difference was instant. Handles soo much better now.

Man....these bars on this car....I can really feel a big difference. The car just feels stiffer all together. The brackets fit perfectly. Thank you! I love them.

anyone running the strut braces?

I have the GM bars on my 04 GTP with no brackets, and it was a very big noticeable difference . The car is much flatter. I will put a set of braces on my GXP, but weighing out my options there as the brackets are costly for what they are so I may just go a different route. A pair of GM braces and mounts can be had for under 30.00 shipped here

Shitty pic but modified otto racing strut towerbrace from a 3800.

Your GXP requires the modified front brace from DRCUSTOMPARTS and the added height of the mounting brackets to clear the alternator on the V8 motor. Most people feel the cost of the brackets is minimal since they are a big time saver doing the install, plus you don't have to drill holes in the chassis which can cause rust to form since bare metal is exposed.

I understand that, but the factory drilled holes in the earlier wbodys with no negative effects so the same can be done here. I have not attempted it yet, but really a couple aluminum spacers and the bar massaged a little would work too. I like your products, just looking for some cost savings to spend money elsewhere as I have more time than money.

do you have a close up picture of this?

Engine and transmission mounts
 

Isn't there someone making solid mounts? Should they be mentioned in this thread?
