You don't need to buy from nitron. any coilover spring supplier (like Faulkner etc)

[Exmantaa]

Gert; you simply need helpers to run 475lb springs on that length of shocks. Contact Nitron or fit a generic helper spring.

[2-20]

I just contact the former owner he told me that this is my problem not his. He say that this expalation is sh*t and won't help me. Are these helper springs for sale by Nitron?

 

So what explanation did he give ?

He may have a car with more weight on the rear (Turbo) so that the ride height was ok for him

[Exmantaa]

The former owner did never drive the car & shocks; he bought it as salvage for a track/race car, but project was abandoned and parts sold. As were these NTR's...

[gertje]

At last he can do is just say sorry, but even that was to much and that is make me angry

[gertje]

But Nothing more over the owner, i try to solve the problem. So i hoing to order helper springs and other brackets for the front

[FLD]

You should just need helpers on the rear IIRC.

And at the front the lowering brackets to get them at the good hight.

[FLD]

I didn't need them.  I found that the springs weren't loose with the ride height set at a sensible level.

sorry Gertje for not having a direct answer to our chat on facebook. I think that the spring rate , versus standard , and the amount of corner weight differences could partly explain why the springs do not compress enough at normal static loads to match ride height expectations.

 

it does seem strange that even with your spring collar at that very high position still , I would have thought the top wishbone would be mechanically limited by the chassis subframe to stop it moving further upwards perhaps.

 

standard springs

VX220 NA = 234 / 268 lbs/in = 42 / 48 N/mm VX220 Turbo = 275 / 315 lbs/in = 49 / 57 N/mm

No problem, i was happy that someone could help me.

The conclusion is that the springs are to hard for the speedster

[FLD]

Would it help if I look out the reciepts for mine and let you know what I have fitted?

[Exmantaa]

The conclusion is that the springs are to hard for the speedster

 

The springs front 0700x225x0400 The springs rear 0800x225x0475 

 

 

 

Those spring rates are perfectly fine for a Speedster/VX220, although with that 400 fronts some 550lbs rears would be a better match... (or for only road use, fit ~350lbs fronts) 

 

"Problem" is that you have the latest spec long NTR rear dampers, which don't foul the top wishbones but really need helper springs to keep the springs seated.

progressive springs might help , at least you could get some preload setup

[gertje]

Thans all for solving the problem. I drive the car mostly on street 2a3 times a year on track. I order the helper springs. FLD maybay other can compare whit your set up

[gertje]

Exmantaa ik had het beter ineens aan u gevraagd he �

[Exmantaa]

Op Speedsterforum vind je bijzonder weinig over dit onderwerp en hier ben je in goede handen.

 

ps,

 

progressive springs might help , at least you could get some preload setup

 

Adding a helper/tender spring (the ones that can carry some actual load) is doing exactly that; creating some sort of progressive spring set-up which maintains preload at full droop.

(as discussed here: http://www.vx220.org...essive-springs/)

 

[siztenboots]

I have helper springs on front and rear since, the ideal length of spring was half an inch between sizes , so I now have 2" helpers which gives me plenty of scope. But with the costs of the helper spring and platform ( plus you will probably need a shorter main spring ), you might be better off with new main progressive springs. Probably just the rears.

Have you also ordered the platforms for the helper springs ?
