Art Morrison vs Detroit Speed.

[David Pozzi]

There is surprisingly little difference between driving Penny and the One Lap Camaro. Penny has a slight advantage due to wider front tires and less overall weight, - and less front weight, but it's more due to those items than subframe construction or other factors. They are more alike than you could imagine. The low tie rod end spacers needed to bumpsteer the ATS spindles are limiting the front rim width for OLC to a 255 tire,. I'm sure there is a solution to it, but for now there are more pressing items on the "list" to fix. Both cars are not fully developed yet, but the biggest issues are solved and we are making progress.

Some of the differences are more in the ease of adjusting a coil over or header or engine clearance. The front rack subs have easier access to the tie rod adjusters, rear steer cars are harder to reach, but I just loosen the tie rod sleeves before setting the car on the turntables, then raise the car to lock them down. I recently did a rough alignment on a DSE sub and really like how it looks under the car. The shock adjusters were a bit tight to get to but not too bad. The sway bar arms are closer to the coilovers which are more inboard and vertical on the A arm than other subs, not a big problem but just different. I like how they tied the rack mounts into the sway bar crossmember. The OLC has more scrub radius by quite a bit, but honestly it barely showed up when I drove it down a familiar bumpy section of road near my house. DSE sub adjusts with shims like a stock sub, their A arms come with delrin bushings which are going to give better control of the suspension than the stock corvette rubber. I don't know if Morrison has upgrades for the A arm bushings. The Corvette bushings are very soft and you wouldn't notice they were causing a cornering loss unles you swapped in better stuff. What I'm trying to say is, most people wouldn't notice the stock Corvette rubber a arm bushings were a problem and wouldn't need to upgrade them, but those who open track or autocross a lot should consider it.

The Lateral Dynamics rear suspension is about as good as it gets for a stick axle car. Super stability and less unsprung weight helps keep the wheels on the ground when you hit bumps. I'm sure the torque arm and DSE rear suspensions are good too.

If you are re-working a stock sub yourself, you might save money over an aftermarket sub.
If you are paying someone to do it, an aftermarket sub is probably very close in cost to a reworked stock sub.
