We are drawing something up to raise the inner TR ends.
So the question-

What if I already have your Coilovers /tubular Arms and 14" big brakes?

And yours will be using C5/C6 hubs....

Which way do I go?

IMCO it would be a good idea if that were done so as to be available a la carte rather than only as part of a complete proprietary system. (Not a fan of add-on plates, FWIW.) And, don't forget us manual steering guys if you re-do the steering arms. My $.02.

The main objective to the spindle besides the drop is to be able to use factory style brakes so you don't have to upgrade the brakes like other kits. With that said, an additional caliper mounting bracket will be needed do big brakes and possibly the rotor hats will need to be changed.

These will bolt up to factory ball joints. Our coilovers use factory ball joints. I like to keep as much stuff Corvette as I can. If you have a bad ball joint 10 years down the road, you can pick up a Corvette ball joint any where and not have to remember if it came off a Camaro/Chevelle/Cadillac etc. Helps the next guy out too.

Steering arm will be a 2 hole, possibly 3 hole arm. We are taking a hard look at how we can change Ackerman.

OK...new hats...C5/C6 hubs...New brackets....What about the steering? (running manual as well) Have to switch to earlier arms or grind down the later ones -or will your tubulars give me any extra needed clearance.

Now I know why this was not done years ago- It aint so easy!!!

The rear- "How about a rear X-member that raises the diff instead?" This would be a no brainer!!!

New steering arms are in the process as well so you won't have to worry about finding another part or grinding on what you have.

We may have 2 different solutions for the rear x-member. 1 is just run a delrin bushing in a factory x-member that will raise the diff. 2nd is a new x-member all together and again we will use delrin as a bushing of choice. I don't really want to lighten up the rear x-member b/c we think these cars need more rear weight.

So, if I use your dropped spindles, I will be able to use stock calipers (or in my case Wilwood D8-6 calipers) with them? What rotors would I use?

I am actually having a set of solid aluminum diff mount bushings being machined this week, but I would also consider delrin bushings.....but either of those only mount the diff more rigidly. I also want to "raise" the diff to help correct suspension geometry on my lowered car. As I already mentioned in this thread, a set of dropped rear shock mounts would help add back shock travel to lowered cars.

FWIW, raising the diff doesn't require a different x-member.

I am aware of that; I plan to section the factory crossmember to lower it over the diff. I was pointing out to Van Steel that bushings don't accomplish this. I plan to both mount the crossmember rigidly, and "raise" the diff.

I've gone a different direction, having acquired a batwing for mounting up my 12-bolt hog head, and for which I'll simply locate the frame tabs as required for height. I figure that I've got plenty of other weight reductions in the works up front that will more than offset the weight being saved here.

The delrin bushing alone will raise the diff.

I don't have an exact date as to when the spindles & arms will be available. As I mentioned, we need to test them 1st. I'm not going to market with a part that has not been tested.

As I previously mentioned, "The main objective to the spindle besides the drop is to be able to use factory style brakes so you don't have to upgrade the brakes like other kits. With that said, an additional caliper mounting bracket will be needed do big brakes and possibly the rotor hats will need to be changed." OE D8s & WWE D8's bolt up to factory caliper brackets & rotors. We are trying hard to make it work w/all factory parts.

Sorry, I should have been more specific. The cross member can be raised up about 3/4" without modifying it, but the rubber bushings have to be removed and the metal flange on the frame has to be hammered flat. Something like this:




I want to "raise" my diff closer to 1.5", so bushings alone won't do that.

I'm game for the dropped spindles. Also give me some more info/pics on the x rear diff mount. I didn't see anything on the website.

No info on the rear x-member yet. I only have drawing but they are not completed yet. We want to do the spindles 1st and get that going.

Any more news on the Dropped Spindle front? Is the goal still to be able to use factory brakes?

Jigs are just about done at the machine shop. I'll have some spindles built here shortly and we'll go to testing. Pics will follow when they are in hand and fitted to our R&D frame.
