Hi Guys,

This afternoon I have been messing around with my mock up chassis and my new build table. Tried wheels up against the frame and wondered typically what should the ride height be?

What sort of distance from the ground to the lower chassis rails should I be aiming for??

Regards, Rob

75-100mm tends to be the norm

Mine sits at 3" front, 3.5" rear, only goes on the track.

On the road I think I had 4" front 4.5" rear.

To set up cut up a couple of blocks of wood to just slide under, tape measures are hard work !

What do you plan to drive over/on? Decent streets only? I agree with 88-100mm minimum. Poor quality streets? 100-125mm min. Track? As low as possible without bottoming.

If you're at the build stage and presumably have already designed the car (or have the plans) there is already a ride height dimension...

Thanks for the comments.

Yes I had looked at it in my design work for CoG calculations and had looked at about 150mm originally, but today I was looking at the real life stuff and wondered what others were running. Havnt fully finalised the suspension, going to kind of develope it as I go to be honest, worked out were the pick up points are and derived the front track, rear track is set by the donor cars original track.

Maybe I'm set a little high then. I'm going to run inboard shocks so will easily be able to adjust it.

So lower the better, good good!

Sorry, I didn't mean "track" as in distance between the wheels, I meant that if you're going to drive the car on-track, that it needs to be as low as possible, short of bottoming.

110mm front and rear on mine but i can come down a bit for trackdays , sump is 12mm below chassis

None of you worried that you're dramatically altering the suspension curves by operating with ~50mm lower ride height dialed in?

When I went from 13-15" wheels I had to make some fairly large changes to the suspension pickups to get the wishbone angles where they should be and move the shock mounts to get the travel right . On the road I think 100mm is as low as I would go .,

Indeed I intend to run 100 on the road, I think lower would end up with too many ground strikes on the UKs roads.
