The GMMG Registry Forum

I was talking with a pal over the weekend & we got on the subject of tightening the cars up.



I got to thinking (always a bad thing) that we've never had the discussion on the Forum so here goes........... Please add your 2 cents.........



SUB FRAME CONNECTORS & STRUT TOWER BRACE?



Do I need them? If you drive your GMMG a lot like I do I say 100% yes. Especially the 435 hp GMMG's & up. If you don't drive them then no big deal.



If you don't drive your GMMG then NO.



Why? I am not sure why GMMG never put them on. I stand corrected - see Aaron's post below. Sub Frame Connectors take out the flex & twisting of the F-Body.



Put some RPM's on your GMMG & shift - notice how the car tends to drift a little? Sub frame connectors tighten things up. HUGE DIFFERENCE!



Bolt on or weld on? I have done both - it's a matter of personal preference. If bolt on you could take them off & move to another car.



Where can I get them? SLP & BMR are just a couple of the companies that have them - (in colors) - search the internet



Cost? Sub-Frame Connectors - $350 & up











STRUT TOWER BRACE?



I'd install one on any 4th Gen no matter what the horsepower- It tightens up the front end & shocks - again a big difference.



It's an easy 10 minute install with a 15MM wrench & deep dish socket (be careful not to break off the studs they will be tight) - Even I can do it!



Cost? Strut Tower Brace - Under $100











STREET DRAG RADIALS?



Do I need them? - One problem with the larger motor GMMG's is traction. The facotry tiresa are too hard & you loose grip



Street Drag Radials are softer & grip far better. *** Be careful in the rain!



I run a BFG - g-Force Street Drag Radials (P275/4017R) on Berger SS #45 & they are great. BUT NOT for AUTO-CROSS!

GMMG did offer sub frame connectors as a upgrade/ option. My car had them installed when it got the PH 2X package. They were $495 on the build sheet. They are welded in not bolted. I remember Mike saying they tried all different brands but their favorite was the " Global West" brand.

Cool - thanks for sharing. Jim

UMI Tower Brace. Best $80 I ever spent. Immediately noticeable. Took 10 minutes to install, and comes out just as quick when I show the car stock.

I have both the sub frame connectors and the shock tower brace. Do it ! It's like a totally different car.

PE41 was ordered with the sub-frame connectors. It also has a strut tower brace. When I get to drive it more next year, I can see how it compares to CETA Blackbird 4.
