Track Day 'Cuda

Looks like a ton of antidive if you leave the upper arms like that. Those headers are amazing. Would take me months just to weld them up, LOL. Nice collectors, Burns
or ? I'm interested to see how the rest of the exh system will run!

Went to your business website. Impressed! There are virtually no shops like that in the Phoenix area I'm aware of, especially that will work on Sprinter vans. The Dodge dealers hate them, Benz dealers wont work on Dodge variants and vice versa,but there's a shop in Casa Grande, about 45 miles south that does all the diesel sprinters for 5 HVAC companies I know( about 150 trucks). The companies hate the distance and travel time, but are at a loss for another solution.

Hi Craig, just finished reading this whole thread. I too run Ron's GT rear and front clip. Already read Greg's thread too. I bought this stuff in 2016 thinking it was the holy grail setup for our old cars. This is my punishment for not staying updated with the threads - I miss out on news like this (regarding Ron's stuff). Will follow this thread religiously to see which of his parts you modify or throw out. (I like how Speedtech modified the LCA in Greg's car). I'd like to salvage anything I can, since those clips weren't cheap....

I can't thank you enough for sharing your experience with Ron, as well as all the details of the build.

I already ripped out the decoupled stuff in the rear and switched to a standard 3 link. I've been scanning the entire internet for feedback from people who ACTUALLY run this rear setup. Talked to multiple people, most notably Tony Ave (who has experience with these in Trans Am). He basically said this design isn't as effective as we all think. His words were "braking stability is much better without it" and "weight and handling changes as it wears".

Also found a video of this setup in a customer car, taking a beating. Anyone know who's car that is? Can't imagine many ppl are running it? Curious how it performed, considering the decoupled setup used in past Trans Am cars was wayy bigger and beefier:

I think if you wanted to put in the effort, it could be made to work slightly better than a standard 3-link only because we use 200 treadwear tires. At the end of the day, I'm not willing to chase setup on a constantly moving target.

That's Ron Ver Mulm's car. Talked with him about the decoupled setup, and he was working with it. He had to change out the lower link compression spring unit with one that had more spring travel and a higher spring rate. He had to send the upper shock back to Advanced Racing Suspension to have it MASSIVELY revalved, from Ron it has like 20lbs. of compression, which is about useless. I'll be scrapping it as well and just running a 3 link designed by Riggin's Engineering.

The De-Suttoned 3 link FTW !!

[andre68]

Really? And this guy called himself a shock expert....

I was ready to throw the decoupled unit in the trash until I found out Derhaag motorsports is running a dampened accel link on their TA car. Maybe down the line I'll modify the accel link to the extent that Ver Mulm did and test it on a track day, since it bolts right in place of the standard 3 link bar....it would be nice to have something cushion the "hit" on acceleration....

BTW appreciate the detailed photos on the ICE kit, I'll be purchasing that soon

Seeing how much the pinion angle changes relative to the rear axle suspension travel... holy crap. It's dumb luck that the splines didn't pop out of the driveshaft!!

When I say "De-Suttoned" I mean that, like Weld and Speedtech did, one has taken the "decoupled" out of the equation and made it a standard 3 link.

Lol yes your De-sutton comment made me laugh. I was referring to the previous comment from Craig about having to re-valve everything. I forgot to quote him in my post!

(in Rons voice) “Don’t worry about the working angles, that’s for street cars, not race cars”

Thanks, I too hate Sprinters. Expensive parts and difficult to diagnose. Basically, whatever codes you have, the problem is something that didn't code.

Thanks, yep, Burns double slip collectors. Also, had them run the X program for my engine to arrive at a primary size and length. Surprised me on primary length and making life difficult to fit!
