Herb Adams former Engineer for Pontiac developed those back in the 70's to go on his Fire-am cars he sold them through a line of parts VSE. He made simple adjustments that yielded fantastic results. Proving his know how he modified a T/A drove it to Daytona, competed in the 24hr race. Great video, well done.
Thank you! I'm actually a fan of people like Herb Adams, Smokey Yunick and the like. They created the cars, and the hobby I like so much. Herb drove that Trans Am to the race and ran it competitively thru the night before it broke the nose on the crank. The only part GM said he was not allowed to have forged in the Super Duty 455. Thanks for the comments.
I got to meet Herb at Road Atlanta, He and his son were showing the Contessa car he created. NPD in Ocala has a Fire Am in the collection. His son and another guy made a new Pro-touring style Fire Am there is a video of it on here on youtube. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-miyVaLD1kcs.html
first time hearing of this product. Really interested in upgrading my 81 T/A 305 sbc Spec Ed with this product now. Great instructional video. Appreciate it👍
There are loads of mods that you may or may not feel when they are completed. This one, I just couldn't believe how much better it felt. Of course that depends on how rigid your particular car is to start. Mine would sag the front end when I put it on a lift.....no longer!
Thank you so much for posting this video...very instructive! I've done business with Dave at PTFB on leaf springs, subframe connectors and an awesome drop base air cleaner (for those of you who have a high rise intake manifold). He is a great guy to work with and he is very knowledgeable. I may have to do this mod....I just hate having to remove the hood! Lol
Giuseppe Verdi thanks for the comment! You are right. Dave is extremely helpful and knowledgeable. I promise this mod will make more difference than any other chassis mod. Don’t sweat the hood, just borrow another set of hands.
I put these PTFB Pro G Braces on my '78, they have transformed the ride of the car, totally agree with what he says in this video. Great video by the way Garage Clinic, keep them coming.
I know it’s an old comment but was wondering if you had solid body bushings? It says on PTFB website they’re needed and I have newer, but not solid. Thanks
Ok, now I want these for my old shoe. :) ‘74 Firebird Formula 400 Perhaps a follow-up video, showing some detail on clearances? I’m wondering if I’ll be able to clear the PB booster and the AC. I know you’ve got PB but my master cylinder and booster are the Corvette style (rear disc conversion).
Thanks for the comment. Yep, I had already changed my M/C and booster to the '81 smaller, lighter booster for 4 wheel disc and there's plenty of clearance. Also, when swapping out the engine, I pulled it straight out with Ram Air manifolds still attached without removing the G-braces. I have not reinstalled my a/c yet, but I understand there are no issues there either. I'd stick with arch supports for the old shoes!
@@thegarageclinic3161 good to hear that it should fit. Of course if I change my original A6 AC compressor to the smaller (lighter!) type like you'd see with Vintage Air, that would also help. My PB booster and MC are different from yours - do an image search on C3 Corvette Brake Booster and you should see what I have. Basically, the booster diameter is smaller, but OTOH it is thicker/deeper, so the MC sits further forward. GREAT video - I did not know about G braces previously. P.S. do my subframe connectors serve as arch supports? :)
You can ABSOLUTELY use your compressor with these. It'll be tight. I've had it off at that time and have a since decided to go more RACECAR than STREETCAR
I've run a length of 1/8 inch steel under the lip as a bit of a 'washer'. Looks better having the braces over the top rather than that mild steel blank.
That is about the only thing I have not seen I'm ordering tomarow. I'm just finishing up my chassis on my 1978 S/E car I did a full heidts suspension did there front sub frame. And there rear 4 link set up. I heard u mention u wanted to make the back of ur car handle like the front well I will tell u I helped my neighbor put the 4 link set up on his 1978 z/28 it is nothing short of amazing with a all iron small block it holds the same lateral g force as a c5 z06 he races it competitively he drives it on the street alot it does decent on coil overs but during his off season he switches to his air ride and it's amazing. I don't know we're u live I live near Cincinnati if u consider the system and I live close would love to help a fellow t/a lover.
@@thegarageclinic3161 Could I bother you to measure the stud diameter for the large and small buckles? I can only find them up to 3/4 and Dave’s response time is very, very delayed or non existent. I’d imagine he wouldn’t give me that info anyway. I appreciate your time and response.
Very nice trans am you have there! Thank you for the vidéo, however i’m not shure about having a mix of solid mount and rubber mount on the sub frame? I think an aluminium bushing set would be a good option with this kit.
It will. My car HAD a/c so they fit fine around the a/c evaporator case. As far as the compressor is concerned (I had removed mine) that would be a non-issue.
I wonder if this will clear the factory turbo on my '81 TA? What brand of subframe connectors do you have? There are so many to choose from, it's hard finding the best designed.
@@thegarageclinic3161 Herb Adams (Father of the Trans Am) is the engineer you were speaking of who wanted these cars to have them when they were being built.
Ultimately I did. And had a devil of a time doing it because the braces were on and the subframe connectors were welded. Really should have done it at the beginning.
@@thegarageclinic3161do the solid body bushings make the ride rougher? I want the ride to be decent and not too harsh or noisy. Im going for a weekend warrior type of setup not race car.
@@thegarageclinic3161im trying to completely redo the shot suspension of my 76 trans am, but i dont know which parts to get. Im so getting this brace.
Dave Barron the ProTouring FBody adjustable G-braces were designed to work with air-con. I have not reinstalled my compressor yet so i do not have first hand experience. I have heard that it’s a tight fit, but it works. These braces were something the original engineers wanted but could not have due to costs involved. They made a MASSIVE difference on my car. Thanks for the comment!
I haven't reinstalled the a/c yet but there is room. On an original car the install would be much harder based on the underwood clutter, but they have been used that way, just not on my car.
