Age old post I know but, I'm looking at ways to uprate the present setup.

Option 1, Buy a LSS damper kit a say goodby to £1200. Girl friend woes when she finds out.

Option 2, Buy a standard set of bilsteins ans a LS anti roll bar. £738.

I've already got exige wheels with A48's so i reckoned by twicking the anti roll bar and fitting a fresh set of standard dampers I could get a similar performace as that of the LSS dampers on their own.

Also I don't fancy wiping the front of the car out on the speed bumps which seem to polute this part of the world these days, I know I would with adjustable ride height dampers.

Feed back would be good

Step 1: £1100 for one way Nitrons new or about £750 newish (check classifieds on SELOC/PH)

Step 2: Change girlfriend

If found a greater step change with the ARB than I did with the Nitrons. Of course it could be that the ARB enhanced the Nitrons and that if I did it the otherway round then I would notice a greater step change with the Nitrons.....if you see what I mean.

Are the current bilsteins broken?

To be fair I think the standard S2 bilstein spring rates are too low for use with R-tyres (cornering forces are higher so you need heavier springs to control body roll).

The LSS as fitted to K-series S2 is pretty good, but the spring rates are still quite low while the damping is quite firm. LSS do have ride height adjustment. For track and road use they are excellent, but expensive.

The standard nitron spring rates are 325/400 which are quite high for road use and you have to fanny about tuning the damper stiffness to work - unfortunately that's a bit of an art form.

If you could get second hand LSS I would have thought that would be a good bet. I have an adjustable ARB on the 135R but have never bothered adjusting it - in the wet I would disconnect it; in the dry I would guess you would have it at max stiffness or close.

Cheers,
Robin

my understanding regarding the arb is its there to help with week spring rates hence higher spring rates require less arb
therefore if you fit stronger springs try the car first before you get an adjustable arb as you may find the std one is fine
i am using 400 / 550 springs and find the weaker early arb is fine on my set up but the type off dampers also have a huge effect
