The Mustang II stuff was a boon to mankind when it first came out! :lol:
The short A arm lengths made it fit the old hot rods well, but they do have shortcomings.

I'm skeptical of what I read too, but for the Super Chevy test I was there and saw it all. Many of the cars were freshly built and had very little test time, issues showed up during the day that needed attention, much like any track day I've attended. I think the Morrison vette was the car I expected the most from and I think they got the short end of the stick by not having an optimum tire size available for the car. All the slalom tests were driven by Nick, who can beat all of us in a slalom contest. Mary did all the autocross runs and drove each car almost exactly the same amount. They also did a ride and drive (with other drivers) to see how streetable the cars rode.

I wouldn't focus on who went a tenth faster than someone else, it isn't a significant difference. If a car was a half second to a second slower, then I'd say it was a bit lacking somewhere, but only on that day with that driver. Change one thing and it might turn out much different. A shock setting, bar setting, tire pressure, camber, caster. I've changed a bar setting and picked up 1.5 seconds, so tuning is a key element that trumps what subframe or engine you have, unless everyone has had loads of tuning time on that pavement on that course. The Super Chevy course had both tight and higher speed left right swerves that would have made for a big long slide or spinout if you got it wrong.

Autocross really works a chassis as far as peak cornering loads, we get more body roll at an autocross than on a road course. This is from the sharper left right turns linked together you often get at an autocross. Go too slow and it takes a completely different setup to get a car around a corner. Especially if that car has a little extra front weight, or if it has a long wheelbase. The front wheels have to turn sharper and on a super tight autocross corner it's REALLY tough on a longer wheelbase car. The Air Ride Chevelle was one of the cars I rode in and was pleasantly surprised by the ride and how it handled.

I think you brought up some very valid points, the product needs to be affordable, have good handling and be easy to install with good durability adjustability and tech support. They have to be streetable because most guys are not going to risk damage to their cars on a race track. But some will and they need to stand up to the abuse.

Sorry for getting this thread off track a bit.

I've got a 70 Camaro that I am plan on starting soon and I've been looking very hard at the Heidts front & rear clip or a modified stock front clip with a Heidts rear clip.

So the question is how hard am I going to push the car.

Not really sure but i do plan on doing some autocross and some track days with the car. One thing that I am certain about is the fact that I am sure the chassis will out perform any skill level that I have.

The main goal for the car would be to have a more modern front and rear suspension that handles and drives well on the street and that I can still have fun with at a couple track days.

If I were to keep the stock front sub i would without a doubt buy the speed-tech upper and lower arms with ATS spindles.

So as of right now i'm still on the fence but that's okay since i'm not starting the project till summer.

David: Thanks for your comments, paticularly concerning the significance (or lack thereof) in a 0.10 second difference in timed results, the differences in how a road course and autocross stress a suspension and car and the importance of keeping your eye on how you're going to use your car.

For my part, I've dismissd the Heidt's product as "hot rod" oriented, and still have some reservations about a handling subframe built arond a 2" drop spindle, but it would be exciting to have another good, reasonably priced option available and I hope Heidt's is or becomes that option.

Oh, and your comments were hardly "off topic."

If you can afford the camaro you can afford a after market subframe.

Has anyone used the Speedtech frame? Ive been thinking about ordering a complete one for my car.

I am using one...but we are a few months from driving the car.

Frank has one on Empty Nest and loves it.

Curious Tony how much did you pay for your spped Tech SUb?

It's no secret ST is one of my sponsors (look in my signature) therefore I did get a price break...but I can tell you this much, it wasn't free! For the record I approached Blake as I was very interested in his product, not the other way around.

Sponsorship or not it doesn't change the fact that I believe in ST's product and that I should be able to voice my opinion without being questioned.....:rolleyes:

Not really i am sure there are many others on this site that have had to take many years to build there cars due to financial strain.

Yup! Ive ben building mine for 2 years now. Saving all my spare money for parts. Its taking forever but whens Im done it will be awesome. Not everyone has 50+K laying around to build a car. They do it in stages.
