Tell me about - Suspension

[LowStandards]

What i basically need to know is how to work out what spring rates i need and also spring length for my Imp project.

The complete suspension will be from a MK1 MR2 which is about twice the weight of the Imp so it will def need changing. Its also going to be a drag car, so i don't know if anyone knows wether they need a different setup to road cars (i'm guessing so)

I'll also try and get some pics up of the Imp, she started life as a 74 deluxe. Now she is just a single skin outer shell using the original floorpan and the rest is spaceframed. The complete suspension and engine drivetrain will be taken from the MR2. Doing some very quick math i'm hoping for a 13.5s quarter using the standard engine!

That sounds cool! If I were you I'd jot down some measurements like weight etc., and talk to a spring manufacturer... I can't think of the name of it off the top of my head, but there's one that tonycocacola used that custom-make springs for a reasonable price. I'm sure they'd be able to assist you get the right spring rate.

Unless you are going for an adjustable set up you might be better of keeping it standard at first and then trying it and see what you want.

Although the weight is halved the standard MR2 is not that stiff as standard so it may be acceptable as it is.

At least if you try the standard set up it gives you a starting point and something to develop it from, especially when you wont really know what the balance of the car will be like until its complete

K,

I was gonna stick it all in the Imp using the same mounting points and dimensions as the MR2 to make it easier. I was thinking maybe a set of coilovers would cure my ride height issues, then its just a case of as you've said gettting the corner weights sorted???

I'm about as good with the tech side of this as my Mum!


Here's a few teasers:
