Progressive tenders for GCs

the plot thickens

I've never actually seen anyone use 2 different spring rates on one dampner. For example, you'd have a 100# "tender/helper" spring that would absorb small bumps and once it is compressed, a main spring with a higher rate would come into effect. It sounds like a good idea but there would be a few problems to overcome. Suspension travel is one, as we don't have a ton of suspension travel on these suspensions. That extra spring is going to take up a fair amount of travel. Then, what about the dampners. It would be over dampned for the helper spring if you tune them for the main spring. Not a huge issue but might give a weird feel, especially in transitions.

I am gonna disagree on just about every level. I would explain more, but I don't have time. And, lots of race cars do run a Tender/Linear spring combo - but most don't understand how it works.

Suspension tuning is a science, not a guessing game.

Doesn't really matter, Matt will be rocking his DSM probably with Tokico shocks and Neuspeed springs or something soon :)

Actually, the car I'm looking at has KYB AGXs/Eibach on it.

Hmm, marginal improvement.

Not like it'll be on there long after I buy it anyway.

If you think its a good idea for this guy to try and impliment a tender spring on his street car, then great but I think its a huge waste of time/effort/money for him to try and do this on his setup.

No one mentioned full-bore race cars. Then we get into a whole other level of shock tuneability (high/low speed adjustments) where the use of a tender spring could be incorporated.

Apples to oranges comparison.

I'm referring to only street-based cars.

If he has time, resources, money and mathmatics, I don't see a problem?

Sometimes it is fun to play around, whats wrong with figuring things out? All gotta start somewhere. :)
