springs

[Mr G]

I have the standard suspensions springs issued with the superlight. I am thinking of uprating them. I used the car mainly for road use (even if the speed is a little exessive0, althought the track days are a frequent calendar event.

 

Any thoughts on the spring ratings to go for ?

My last superlight i had 300 front 170 rear with a 5/8 front roll bar very good all round

Thanks Fred.

 

Can you describe how the ride was on you superlight, before and after uprating the springs to 300/170.

Personally I would find 300/170 too stiff. Stiff = fast is not always correct. It is down to personal driving taste though. There is no wrong ot right.

I run 260 front and tried 180 rears and am now trying 150 rears.

I know some of the SLR and VX race boys run bonkers stiff all round but as a good all rounder a slightly softer setup can pay of esp if the weather is changeable.

The ratio of 300/170 is very close to my chosen one. There is definitely a lot in the ratio of stiffness front / rear for that 'right' feeling of balance.

I run 300/170 springs and would describe them as 'track orientated' but OK on the road. However I'm using Leada's with adjustable damping which can be backed off for the road. I would expect 300/170 on standard Bilstein's to be too stiff for road work.

Just changing the fronts to the ~250lb/ft range works well on a Superlight on the standard dampers. You will need a helper spring to set the ride height correctly.

Dampers and springs, one of the pains in my life!

 

I had some new Spax dampers which were way too stiff. I thought it was my spring set up...325 front, 185 rear. I then went to 275 front and 150 rear, still wy too stiff and did what i should have done in the first place and investigated the dampers at the same time. Spoke to Spax and got them to revalve. Put the 325/185 combo back on...still too stiff....now I 've just gone to 275/150 again to see if that will get me where I want to be. I'm looking for track orientated, but still retaining teeth and fillings on the road!

as you can gather by now it all depends on the individual .my set up was good on the track and on the road but a little wanderer over 130 on tight country roads i tended to spill my drink 😬

Fred, was that the Scottish grape?

 

I switched to R500 dampers (almost new from Blat Chat) and 250 fronts but can't recall the rears... I do know that it is what Caterhams recommended for R500's.

 

I actually think they are a touch hard for our less than smooth Sussex lanes but for me there great advantage is that I don't bottom out - especially on the farm drive.
