Question

My new Scoob was fitted with Cusco coilovers by a previous owner. I've no idea what springs are on it, but it seems a bit hard and underdamped for UK quality roads, so I'm planning on taking the springs down a notch - probably to 275/225lbs at first but I'll experiment.

To save me the hassle of measuring the springs, does anyone have the inside diameter and free length measurements available? Failing that, does anyone know who the UK distributor is?

I think they're either 02s or 02-Rs.

Cheers

I *believe* they're 440 and 275 if they are the standard springs. It certainly feels about that hard - especially at the front.

Can't remember inside diameter for the Cusco. Think it's 65mm.

If it helps it's different to the spring diameter of Leda's which i think are 2 1/4" or 60mm.

Spring free length on mine are 8" front and rear.

Took a front and rear strut off last night to get the measurements, thought I'd post here in case anyone has the same question as me and does a search...

They are 65mm internal diameter. The platforms will take up to a 9" spring. The dampers are very plush 40mm units which obvously cost the original buyer a bob (yen?) or two!

Mine were rock-hard 6" springs, there was NO DROOP whatsoever - hardly surprising that it was so skittish. There were no markings on the springs (except a daub of orange paint) but having taking measurements, the calculated rates were 420lb and 380lb.

I've ordered a set of 250/200lb spring 9" springs, so we'll see how they work - I don't want it any harder than it needs to be. I'll report back once they're fitted.

I ordered the springs from Faulkner's through Demon Tweaks. They were about £25+VAT per corner I think. I'll post back here to let you know how well they work with the dampers.

Do your dampers have adjusters at the bottom with the numbers 1 to 4 on each corner? Are there only 4 settings or are they quarter of a turn markers? They seem to just spin and spin as far as I can tell.

I now have the springs at home. Doing the work Monday night, along with the fitment of solid rear drop-links and an 'anti-lift' kit (both Whiteline).

I'll post a bit up about the ride quality on Tuesday, but won't be in a position to report on the handling I have the geometry and damping set up properly.

Sticky can you tell me what you bought? I'm still getting used to the Ledas but may need to put less extreme springs on the STI 5 also

Ive emailed a few people from the two cusco threads on scoobynet and have had soem good response, cheers guys.

Just to confirm, what is the standard sti6, any type r spring rates front and rear.

I want some slightly stiffer than factory standard, so was thinking off 250/200 like Micky.

STi6 standard spring rates are 237 and 195 lbs / inch. That's the stiffest of any factory Scooby

and sum people complain that there a bit to stiff for uk roads

so that sounded about perfect as a base for my suspension

200 rears are as good as considering you cant get the exact figure, i wish i wasnt so skint so that i could get the rears bought, i was really hateing the way my car drove with them fronts fitted

i could sqush the 250 fronts a bit by hand, the ones i took of were like fooken tubes of steel

Unhappy

decided to wait and see what rich at powerstation thinks on the coilovers, ive set them at setting one which i hope is the softest.

I have also took some pictures of both front and rear struts, it seems that the springs are very short and the height adjuster is wound up very close to the top of the strut.

Last night I fitted the new springs, anti-lift kit and solid rear drop links. I haven't cornerweighted it yet or reset the geometry, but I can say that;
1) The ride is obviously much better, although still very firm
2) The handling is much more predictable
3) 250/200 is a good balance front-to-rear
4) Thanks the the rear drop links, the turn-in is transformed. It's a go-kart!
5) That rear bolt on the lower control arm is a b1tch

I may experiment with spring rates a bit further, as I tend to prefer the softest rates I can get away with without allowing excessive pitch or roll.

cashy: do you coilovers have 1-4 on the bottom, and spin freely? Mine do and I find it a bit confusing. Are there only 4 possible settings?
