Drop Spindle Discussion

Anyone besides me notice that Callaways Corvette C16 uses supplemental coilovers to the composite leaf springs exactly like the RS kits uses the springs to supplement the torsion bars?

[Grant]

Cchan, Idon't think that will be necessary. I learned alot about your setup already with your post.

Louis, I didn't know that, I thought the RS kit was one of a kind. I wonder why Callaway went that method...I thought stiffer leaf springs were easy to come by. Ride quality maybe?

And the PM is fine. After the track event on Sunday let's do a swap.

One key aspect is that you can leave the coil-overs partially unload (red tender-springs not fully compressed.)

This has the torsion-bars carrying ALL of the car's weight, as well as ALL of the initial suspension compression - leaving you with a completely stock ride-feel - until you load a corner, the rattle-springs compress fully and the RSR coil-over springs are activated...

[Grant]

Hey Jon, are the rear springs progressive? Does it feel like the front end is soft at first but the rear end is fully stiff? Or not?

Grant,

You can look at the photos. The coil looks to have a linear rate, IMO.

[Potenziato]

The RS springs are all linear rate front and rear. The little spring in the front is a helper spring that does nothing other than to maintain tension to keep the spring held tight.

Can you adjust preload on the RS dampers?

also LOLOLOL on Colin Chapman references!

So, I don't have my comupter with me this week but, here goes:

75evo,

I thought coil diameter changes as well as the spacing of the gap between coils had to do with linear/non-linear. I'm wrong though

Monty,

My intention is to try to dial in my suspension before I go killing expensive tires with excessive understeer/oversteer. Then I'll be able to afford used Hoosiers or something

What's so funny about the Chapman references?

@Louis - I think the way a car will handle at the limit will be roughly the same whether you have cheap or expensive tires. I know steering response won't be as good with the cheapies, but I don't think and understeering car will turn into an oversteering car with a trip to the tire store. Eagle F1's are baller!

And, I think Louis' spring rates were too much for the dampers. Felt a bit underdamped from the short ride I got. Maybe with softer springs they'll be just right? What do you think Louis?

Do you mean steady state cornering? Because you could have the rear end come out under power with the road tires, and not with the slicks. You don't mean that right?
