Default A Subframe to Out Do Them All!

We all like the assurance of knowing we're equipped with what it takes to win. Can you say that about your current suspension?

For those of you who are serious about tapping into that type of capability, we've listened to what you wanted and have produced a suspension system that is intended to be better than anything else, period. Designed by Speedtech and Ron Sutton this system is optimized for street drivers and racing! The ExtReme suspension gives you greater control and more tire on the ground during hard cornering, and that translates directly to lower lap times. Check out more at Speedtechperformance.com and get your ride on the path to the winner's circle!

We designed our mounts and headers around the LS, however we have had customers use both small and big blocks by having custom headers built. We are also working on the new generation LT mounts and headers and will have them available soon.

I got a little more info from the sales guys. When this suspension was designed the main goal no matter what was to totally optimize suspension geometry for literal race car like handling in a street cruiser, building the suspension based on number goals and a new spindle design. To meet these goals one compromise was to locate the rack slightly under the engine. Combined with seeking the correct driveline angle in a super low chassis meant raising the engine slightly. One reason we focused on the LS was because there would be no issues with running one under a stock hood. By the time you consider an aftermarket intake height plus carb plus air filter, a big block would likely require some sort of scoop. All ExtReme products share the same basic frame rail design where the engine is located. I learned our customer who put a big block in an ExtReme frame was in a C10 so there wasn't any hood clearance issues.

There is 28" between frame rails at the front crossmember. We checked online and found some good dimensional drawings for engines on a google search, you may look up LS and compare to Big Block and then take some measurements of your current set up to see if it would fit. Our phone number is 435-628-4300 if you want to chat more specifically about what it might take to slip one in there. Just ask for the Tech guys.

Are they all designed to allow for the use of factory wheel wells?

fender openings yes but inner fenders, no. These cars, for example a 1st gen Camaro, are tight at best using a factory inner fender with a decent drop and anything much more than a 255. To squeeze 315s in there and maintain a 30 deg turning radius we had to create widened front inner fenders which are available on our website.

Hey Ben, any chance you guys will offer widened inner fenders for GM A body?

you can use the factory inners, with some trimming around the shock mount, but they will be the tire size limiting factor with the max tire being a 275.

probably not. the 69 GTO we did was pretty easy we just split them and added a 2" wide strip to them. the problem is there are so many differences between the models and years. and it is not our core business. we have found that the 69 Camaro inners are a really good start and then modify them to fit your application.
