how much thread showing?
Tried posting recently and got no replies to answer question so thought I'd try again as searching old posts has not given me an answer.
How many threads or how far up the rear shock was your spring seat? Seeing we are having a spell of nice weather I thought I'd finally get
these rear arches fitted.
Last time I tried I had a lrge 3-4" gap above the tyre one a 15" wheel so thought maybe lowering the car slightly would help.
At present there is around 1.25" of thread showing so roughly how much thread do you guys have on display on your rear shocks under the spring
seat?
Many thanks
Nigel

Hi Nigel,
Apologies for not getting back to you with this info. The wedding left a bit of a blur in my brain 
Just been out and checked and I have a 50mm gap between the top of the rear tyres and the lower edge of the wheela arch lip. On the shocks I have
roughly 20mm of thread showing below the adjustable spring seat.

Edit to say...
Standard MK Indy chassis with MK supplied Pro Tech shocks, Pinto engine weighed yesterday at public weighbridge @ 600kg

it will depend on lots of variables eg shock lenght, free spring lengths and spring rates. adjusting the spring base screw will add preload to the
spring and adjust ride height only, best way is to decide on your desired ride height which some go as low as 125mm road clearance and then review
rear arch location, make sure the springs do not become loose under full shock extension, also considder if still in construction all the parts you
still have to fit will add weight and compress the springs more reducing ride height. lots of questions but not a simple answer to your question.

cheers for the info Nick much appreciated. Hopefully now I can finally get those arches fitted as it'll save them getting kicked around the
house by Swimbo

I would have thought the best thing to do is take the springs off and find out where the wheel comes on full bump. Then this set's the lowest
you can have the arches? Else you might foul the arch on full bump?

I'd do the above but add 1/2" to an 1" just to be safe.

Mine rubbed on the arches when I dropped the rear height to 4.5" so I stripped the shock down and added rubber bump stops to stop this.
Wheels tight in arches now, you do not notice the bump stops when driving as ot still leaves a couple off inches travel.
Distance on the spring seat is immaterial, I set mine up with just a driver so they vary across the car.
Just wind up or down until you achieve the desired ride height.

I agree with him above
Everyones cars (homebuilt ones at least)will have different places where shocks are mounted, where arch go etc so I'm afraid you q a bit
subjective
