Well in a sentance; "you get what you pay for"
The experience i had/am having with isnt great. Got the full set inc rears and put them straigh on with new renault top mounts.
I knew they had a shortened damper so continuous lower ride heights are possible without damaging the damper, but the springs they supply are very short. I set them up with the ride height about centre of what i thought they could do. spring cup a bit less than half way down body. Dropped the car to the ground and couldnt see the top of the tyres, only the rims. jack wouldnt go under chassis rail and got about 1/3rd lock. No good.
Then raised them right up as high as they would go. Ride heaight now about the same as standard shocks with -35mm springs. Pretty spot on. BUT the dampers are on their end stop so when you go over bumps the car picks up a wheel and skips around. No good. By the time i had done all this, one of the seals had dropped all its oil out. Took them back to AVO and they replaced both seals and re-filled dampers (warrenty). They didnt seem to understand i wanted near standard ride height (what if i wanted to do a road rally? the car would be smashed to pieces) and the car handled badly if they were set anywhere near the end stops. i was told this is what people want so they can drive round town scrapping the floor. Not for me im afraid...
I go some helper srpings and re-fitted the whole lot. Now i have the height i want and the rate is about right, so they could have both been low on oil from the factory.
Oh, and the rears are a lot shorter so again, the back has to be quite low. But i took mine up a bit as it was too low (lofty will tell you!)
Now i am happy with them, but it took a while to get there! I have run bilstein and proflex coil-overs before at 4 times the price so maybe i expected too much? Also I have a friend running AVO coilovers on a 2wd cosworth and he cant fault them, ride height is spot on and car goes right up in the air or scrapes the ground no problems...
Never mind, will try differnt ones next time. Least they are right now though...
