Saves petrol as you dont have to give lifts to people  (given you still have rear seats)

I find ride comfort on the road is awful!
But for me where the car is used more on track days they are pretty good, but only in the dry. For my car they make the rear end a little bit more oversteery and twitchy rather than under steering in general, so for me they ae good.
But in the wet they are too bad and I switch to my 40mm's which make the car more ballanced.
Oh they do look good tho.

it all depends on what rims, tyres, off sets and arch work your car has it cant just be a general question really
ime 90mm down at the back now and have a sub and amp set up a full tool kit and my cleaning gear in the boot and can get away with 2 people in the rear but then i am running 145 60 13 tyres on a 13x7 so my profile is much smaller

yes if you modify the arches enough with et45-et49 wheels and choose a tyre with sloping sidewall then passengers should not be a problem in my opinion.
ive not ran my -90mm springs yet but i did use my fk springs without the cups and my stripped corsa still sat at about 80mm with them and tbh i did'nt notice any difference from the -50 spax ones i had before them

My -90mm springs use a very low poundage wound spring. the lower poundage means that the weight of the car will help get the car down lower than with a normal spring.
Most aftermarket rear springs for corsas are about 250-260lb. typically a 90mm rear spring will be about 200-220lb. This gives good ride quality but the back end does go a bit soft but helps with handling in the wet.
A standard corsa rear spring is about 170-180lb depending on the model.
On a corsa the actual ride height on the rear isnt greatly important to how it handles due to the design of the rear beam. Its more down to the damping settings and the spring poundage. If the spring poundage is too low the back end will feel wallowy and unresponsive, if its too high then the back end will feel skittish and tend to oversteer in the wet. On tighter bends the latter option is great fun and the car feels a lot more lively but on faster sweeping corners the car becomes unstable.

whats the best option in your eyes? i want it low on the back and ill be down -60mm on the front, but i dont want to sacrifice any handling performance? my allots are et49 and have 195 45 15 tyres? i also need to be able to take 3 people in the rear

tigerseal will hold anything to anything.
if you need to have 3 people 'in your rear'  then your better off with a higher poundage spring, this means that the springs wont compress so much under load. something like a 6 inch 260lb spring would be ideal. will sit around -50mm with a standard interior.

 im getting abit confused.
i used to have -60mm on my old corsa and with 3 in the back they were ok and i didnt even have 45's on then!
I want a lower drop than -50mm with standard interior i also have a sub and amp this spring stuff is tricky

90mils a lot more bouncy than 60s ive found. Didn't feel a lot different handling wise tho, but this was on the road, not on track.

dave whats the best poundage with a -80mm spring ?? i want it to handle the best it can at a -80mm drop?? and mk4_boy has the same profile tyres as me so they might not scrub that much?

why not? well forget 80 now, if you were to order a spring for yourself at -70mm what would the pundage be? and you had standard interior

I had Softstars on my GSi Offset ET49 with 195/40/16. took 3 Grown lads in the back all the time. in all fairness it was riding on the struts, but it was drivable no scrapes, and no arch mods what so ever.

70mm will be ideal witha 225lb spring.
