Here are the wheels going on the car



and here is the 2nd gen Teaser

Wow is there a link to this?

[Moreno1]

Let's bring this to the top

[Redemption]

Id like to hear what these are going for. Thanks

I'll send you a PM in a sec

Thought I'd share this video with you guys. I think it very well sums up the advantages of a penske shock absorber. I'll also add it to the OP.

Im curious about Penske drag racing version front and rear for our heavy cars

[Moreno1]

Just thought I post pics of the shock hats Justin design to solid mount the Penske shock.

Fully tig, almost to pretty to powder coat.








A little over kill! They are even welded on the bottom.








I think theirs two sets left at the promo price.



BTW, spoke with a guy yesterday who building a z/28 track car. He has 32 years of NASCAR experience. They have their own shock dyno and rebuild all types of shocks. His comment was Penske was the best dollar investment we could have made.

Getting these installed on Monday! Thanks again Justin

How much for this setup?

[blackoutVIII]

Nice looking product. Justin and Nathan, keep up the good work. Everyone is a critic. I have been following you guys for a little while. You are always giving good info for us customers and gear heads. I personally am in the middle of wanting to upgrade to the 1LE suspension kit for my 2011 2SS or something else. I am not gonna be an all track car, just everyday driving with a few spirited sprints on curvy roads along the way. PM me if you have some info to share about my future suspension upgrade.

Justin and/or Nathan,

Thank you for a great post.

In regards to the dual adjustable dampers:

What is meant by wide range of adjustment?
Are we talking about a full 90/10 drag race performance for the front and adjust to a full road race stiffness stability for the road course? Or is this something more in between but where in between?

I am just trying to correlate this with other known levels of performance while not comparing brands so that there is a better idea of expectations. Of course, I am speaking damper performance only where as springs would have to be a constant such as street performance on both. An actual road race spring would not allow optimal transfer of weight like a drag race spring will due to the differences in design just like a drag race spring would not be optimal for road race.

Hey PoleCat,

There is a wide range of adjustment so that the user could tweak and tune the dampers as he needs. You could certainly use the dampers for drag and road course, and they will still be very good for both, but anyone that says a standard shim style shock could be optimal in both would be lying. As in the OP, all dampers have a force curve, in which damper force is a function of piston speed. The force curve is designed by the shock tech according to the desired uses given by the customer. The desired force curve for a road course car compared to a drag car will be drastically different. Yes you have the adjustment knob, and yes, there is a very wide range of adjustment. However, these adjustments are not meant to take a road course car to a drag car; their purpose is to account for track conditions, spring rate changes, fine tuning and balancing of the car, etc.

I suppose the future is near with magnetorheological shocks on the up and up, where we will be able to tune shocks to be optimal for both purposes, but for now we are constrained by the laws of physics and fluid mechanics

It sounds like what you would need is a street packaged set up to use for several different purposes. While of course, these are not going to be as optimal as either a drag or road course package, they will still be very good for all, and you would not be disappointed.

You received a design that was changed due to Pratt & Miller requirements and obviously won't work with your setup.

Can you explain what changes were requested by Pratt & Miller and why?
