Ok idiots guide please... I have a Mk2 MX5.. (this one).. It has coilovers, it's just to low, it gronds everywhere and there is way to much camber on the front for me, I want to keep it looking low but give it an extra inch or so up maybe as much as two, I also want to make it more level... Is there a procedure to get the best setup or is it just keep winding them up till you get the height you want.. I'm guessing they're gonna be a bit siezed up as well, any tips for getting them moving? Chars!

Measure the current arch gaps to see how even they are, then wind them up by the extra amount (give or take to level it if needed).

MX5s run roughly 1.6:1 spring ratios, so wind the spring seats up by about 18mm to get the inch you desire.
As for siezedness, give then a good wirebrushing (this works better for going down though, you can't properly get at the threads above the spring seat without taking the springs off) and hammer them with proper penetrating oil a few times over the week before you want to move them.
The spring seats/adjusters are usually aluminium which expands a lot more with heat than steel does, so a general warming all round with a blow torch will help.
If they aren't gonna move on the car, take them off (you won't need spring compressors for coilovers) and drop the whole lot in some diesel for a while.

On my old MX-5 I found it much quicker and easier to remove the coilover and adjust it off the car than even try and do it on the car. Because of how the shocks are mounted you won't mess up the geometry at all or anything. I'd rather undo 3 bolts than have to adjust the spring seats 1/3rd of a turn at a time, plus what seems like a seized seat on the car is often barely even noticed once they've got one end held in a vice.
As Cobblers says, the're not directly driven, 1.6 could well be right for the ratio but I thought I remembered it being different front to rear? Either way, the cars ride height will change more than the amount you adjust them by.

Well, that was easy, not siezed in the slightest, wound them up 20mm and now it sits puuuuurfick!
Boshed them over with PTFE grease for the time being to keep the threads lovely, is there a recommended goo?

Whatever you put on them will end up washed off or full of grit after not so long. Spray on copper grease seems OK, just wipe the worst of the shiz off and regrease them a few times over winter.
