Hi Jeff,

Correction:

I misspoke earlier about the WMS-to-WMS dimension on the new Speedtech 1st-gen subframe. I did start with a clean sheet of paper to design the geometry, so I didn't think the WMS-to-WMS dimension was the same. But it is. Not intentional to keep them the same. Just worked out that way.

So, it's been a while. Updates?

So if I have the Grand Touring suspension package will any of this transfer over to the new subframe?

I think someone asked them before and they said no. Its an all new design and everything is different. I'm still dying to see some pictures of the new subframe. I'm ready to pull the trigger but want to see a completed subframe.

You guys are funny. Blake told me if we make an announcement of what is coming & take pre-orders ... guys will expect it to be ready in 2 weeks. He was right.

I said "naw" (southern accent) "surely they understand building completely new suspensions and frames takes a lot of time & effort." I was wrong.

Speedtech is building 6 new designs ... 4 full chassis ... and 2 front clips. The first full chassis for the 68-72 C10 trucks is almost done. Several Truck chassis are already in production. The 1st-gen F-body clip for 67-69 Camaros & Firebirds is in the prototype stage. They're checking fitment, working up headers, checking trans tunnel clearance requirements. We've pre-sold 6 or 7 I think.

I'm glad you guys are interested. We appreciate it. We're not going to post photos until it's done. Cause sure as heck if we post photos before it's done, something will change. Murphy's law you know.

No, sorry it will not. When Speedtech commissioned me to do this project ... we discussed using some existing parts ... but it would have limited what this new package is capable of. So we agreed to start from a clean sheet of paper and build the best geometry, best steering, highest grip front suspension available to the Pro-Touring community. I even modified the spindle.

Everything is optimum ... from the low scrub radius, ackerman, roll center locations, camber gain, caster capability, caster gain, jacking effect, anti-dive, etc, etc, etc. This thing is spot on. The front end grip will be the best you can bolt on your car. To get better, we'd have to shove your engine back 6-8" under the firewall & build a long arm GT race car front suspension.

But the new Speedtech stuff will drive excellent on the street, have great manners around town, be tough enough for city streets & with the right shocks be a smooth riding cruiser. Until you turn the knobs & adjust the sway bar links. Then it will be a mean handling autocross & road course machine.

It's always two weeks Ron.


Can't wait to see this thing.
