Bandit Posted December 31, 2020 Report Share Posted December 31, 2020 Curious what the impetus for this is, especially since it is all of 10 points. Cheaper than camber plates. Some certain car need it? It says "bolt on" so can one cut their frame off and stub a fabricated subframe on with bolts? I mean for my ride that would be cheaper pointswise and really allow some radical suspension work. Also, for those that do not know, aftermarket subframes are available for 1st and 2nd gen Camaro's that allow the use of C6 front suspension. Just in case someone needed a little extra incentive to build one of those. Quote Link to comment Share on other sites More sharing options...

If your subframe made you run different suspension elements you'd also have to pay 10pts a pop for those each. 1 Quote Link to comment Share on other sites More sharing options...

So? For 80 points, including the sway bar, one has a C6 front suspension under their ride. Artificially lowered VPI cars can swallow that without issue. I'm more curious what made the BOD think 10 points for a front subframe was a good idea. Edited December 31, 2020 by Bandit 1 Quote Link to comment Share on other sites More sharing options...

And you wouldn't even have to do that much if you didn't want to or didn't have the points to spare. With a 10 point subframe you could move mounting points and optimize the geometry while reusing all the factory components. 2 Quote Link to comment Share on other sites More sharing options...

It was most likely an elaborate scheme by the BOD to provide a points incentive for you to finish your car this decade and actually bring it to road america. Instead of questioning rules and impact of said rules from someone who has yet to race with the aforementioned rules. 2 1 Quote Link to comment Share on other sites More sharing options...

That seems like a helluva lot more than I interpret a "Tubular front sub-frame/K-member (bolt on only)" to be. That's part of a $6000 TCI IFS setup and I'm pretty sure that it doesn't "bolt on" to the chassis. 1 Quote Link to comment Share on other sites More sharing options...

I built a sub-frame back in college for my VW to adapt a Triumph front suspension, and it bolts on. Cost maybe 100 bucks. 1 Quote Link to comment Share on other sites More sharing options...

Camaro's have always been unibodies. https://www.racingjunk.com/news/installing-a-new-front-subframe-on-a-67-71-f-body-part-1/ If they are not talking about a subframe then what are they talking about? It says subframe right in the rules. *All of the Pro Touring stuff is vastly overpriced. Control arms from Speedway are about 20% of what Detroit Speed charges. The Speedway parts just aren't as pretty. eta-Video showing the mounts under the car. Edited December 31, 2020 by Bandit Quote Link to comment Share on other sites More sharing options...

It goes between the lower control arm mounting bolts and adds support to the lower front end. I'll see if I have a picture of it, I have it on my build for 10 plus the upper strut braces at 10 each. I opted for the rear roll cage bar for the rear one and added that with the Aero mods. Edited December 31, 2020 by Timothy G. Elliott Added photo hard to see but under motor.

wvumtnbkr Posted January 1, 2021 Report Share Posted January 1, 2021 (edited) A subframe is the part that bolts to the frame that typically holds the engine mounts and the steering rack. The stock frame is still there. Lemme see if I can find a pic.... https://images.app.goo.gl/HCMVDS1dERCdeWgY7 Edited January 1, 2021 by wvumtnbkr Quote Link to comment Share on other sites More sharing options...

Add up the swaybar, lower control arms, upper control arms, springs, spindle, steering rack, etc... it might be doable for 80 pts. Quote Link to comment Share on other sites More sharing options...
TimS Posted January 1, 2021 Report Share Posted January 1, 2021 Seems in a unibody type car without a “frame” the cradle that holds engine and suspension would be “subframe”. Mustangs, early Camaro, RX7, etc. fox mustang and Camaro have a lot of options as these are popular. All the additional parts like control arms, rack and pinion, etc may cost to many points to be useful but if they utilized the original parts and just changed the geometry it may be worth it. 2 Quote Link to comment Share on other sites More sharing options...

Seems a step towards tube chassis, which I don't think anyone really wants. The extremely low point cost is what I find really baffling. 1 Quote Link to comment Share on other sites More sharing options...
