The idea of coil over is that you can put the car on some scales and get the weights evenly distributed. you can't do this with a fixed height system. If doing any track work, getting the weights right is very important....this should be done before chasing any "handling issues" you may/will experience.

Coops - any model gemini as far as I know. I've bought 3 sets over the years and they've all been the same. Unless you're going crazy low, you won't have a problem.

corner weighting is a pretty sophisticated setup 'tool' (for want of a better word) and best left until you have done all the basics and have a full on race car chasing every last ounce of performance. Complete wank on a road car.

Hey Rainer, sounds like Warwick did your shocks? He's a good shock man alright - does some of the fastest formula libre hillclimb cars in the country.

Right on the moeny Harry. Warick is very good at it, he wouldnt let me buy anything below Koni inserts .... He really enjoys doing them on the side as he doesnt do many anymore with his power steering business. Then took the setup over to LEDA suspension with the old Guru Bruce with all the old alignmnet gear! awsome stuff. Im sure you will take the coupe over to Bruce at some stage??

yeah, Bruce did all my alignments on my old coupe and the GTR, so the new coupe will go there eventually, but I haven't even driven it yet!

might be going out for a practice at Morgan Park tomorrow

on the gemini springs use springs from a td 1977 onwards ( square headlight and chrome bumber bar) as this was the first with RTS and variable rate springs

So what part on the shock bottoms out?
I'm guessing the top of the shock insert tube....

who told u that???
i would never set the car to a different height on the right to the left unless racing around a speedway track or oval circut....

corner wieghting should be done by moving components, adding weight etc... not using the coilovers.

Coops,
look at how much suspension travel u have with the ca18 in it. maybe 2" travel before u hit the bumpstop!! This is bad already.
if u don't want to lower the car no worries get some decent inserts and harder springs.. maybe the gemini progressive rate springs are heavier than the 1200"s??? it will handle better but is that all u want???

if u want to lower it a litte bit it will drop the centre of gravity+++, but u are going to need a lot more travel to drive on a track, even on hard braking without bouncing on the bumpstops.. that is unless u are running 300p springs???

shorten the strut, weld on coilovers, get decent inserts, 175p springs minimum..

yep thats right..

don't jack up the car..
Look for the shiny bit measure the length, that is the travel.. not much left with a boat anchor bolted to the front

well doesnt the drivers side need to be slighty harder/higher or set differently?.. as the driver is sitting on that side. average 70kg but sould be someone up to 100kg +.... This would have to be factored into setting up the suspesion for race track?

How do u know that the drivers side is heavier until u put it on the corner scales and jump in??

u need to move components/urself to shift the weight and at worst u add weight.
