I figured the non-ajustable braces matched the correct f-body dimensions, so if your car is straight they should fit with no problem. Of course, that doesn't explain why there are adjustable braces.

I've got PTFB solid bushings and subframe connectors now. The car tightened up pretty good with just those two items. I have the G-Braces, but not installed yet. If it gets even stiffer, that will be great! Theoretically it should, of course, but I'm not dissatisfied with the way the car feels now (I was before the bushings and SFCs).

Guys, this is a NastyZ28 sponsor sub forum. At least show enough respect not to discuss knocking off his stuff in his forum.

edit: I deleted the posts in question in this thread.

Feather-light suspension, Konis just couldn't hold. I'm so glad I took a look inside your showroom doors.

because these are 30-40 year old cars with varying tolerances, both from manufacturing intended leeway and wear. These cars are not 2011 Camaros where everything is much tighter and new.

I have an 81Z in the driveway with a visibly bent subframe and yet has straight sheet metal. My 77Z is in a similar state but the subframe issue is not as pronounced, at least visibly. In my 77, Dave's 1st design fit the LH side perfect, but the RH side had issues around the AC box and general fit. After discussion with Dave he thought because the original prototype was on a firebird. The next design fit the RH side much better. However the frame issues cause me more trouble so I traded up for the adjustable ones, which I have had no time to install yet.

So IMO that is why the adjustable ones exist. I'd also guess that is why DSE has not bothered making ones because of the tolerance issues and the resultant service issues.

LOL... See what I mean

ETA. I will add that they make a VERY noticeable difference in handling.

For a seat of the pants difference, I believe this is the most notable thing I have done. Even more so than welded SFC and solid bushings.

Now to take further advantage...

Todd, Scott get on it!

It's been a good exchange. I'm ready to try a pair of the adjustable ones if they are in stock and ready to ship and they'll take them back if they don't clear my brake master cylinder and booster.

I wish they had the adjustable ones when I bought mine. I want to say that Dave told me they were on Pontiac F-bodys first. My pass side one I cut and welded the outer tab to re-position it.

I think that looking at the new adjustable ones he has...they seem to be a little more stout looking.

You can't go wrong with them, this is a no brainer mod as far as I'm concerned. Anyone that says different....well...they just don't have them on their car..>>>>>>>>>>>>>>.Ken

Orange71 said exactly what I say about adjustable g braces from PTFB. I added them and my steering was "quicker and more precise" . My 71 has a large power brake booster and factory air. They fit perfectly.

Yes, I auto cross, and run road course track days with my car. Tomorrow we run scca, and next week we run a road coures with pro auto sports.

Having just g braces as an addition to your car will put you in esm, or for a better pax, cp. So, the scca must think they are a huge benefit.

Wonder if they'll clear the dual 9" aftermarket boosters and master cylinders? They stick out farther from the firewall.

i really wanted to get some of the adjustable g-braces but dave said they wouldn't clear my BBC with tall valve covers and small block motor mounts. sucks because after the posts on here i really wanted them to go along with my welded frame connectors and solid bushings

I have new subframe bushings and subframe connectors and those really didn't make a huge difference in the way the car drove. I used Hotchkiss subframe connectors. Not a big PTFB fan.

When I put the G braces on it was an instant improvement...let me tell you. NOTHING I have done to the car made as big of a difference in the way the car drove...handled..went over bumps..how much flatter and even the car cornerned. The car going straight down the road even seems to respond better to the road as far as steering and ride goes too.

Drivers side went in no problem.the pass side fought me hard. Had to cut and weld one of the ends to get it to bolt up, but no big deal. This was before the adjustable ones were offered BTW.

Alright, you convinced me to try em out.

i have also heard you can benefit from the adjustable g braces because you can preload them.
