looks to me like its all down to money.
Osravs and billies are the top of the range for separate springs and dampers.
coilovers on the other hand seem to be a much more expensive proposition, to get the same quality of ride/handling you still need to go for top of the range i.e leda
Or have I read all these threads wrong?

If I would do it again I would not bother with coilovers, I think the osravs and eibach is probably the best all round handling package. In the case of traction you want the front as soft as possible and the rear stiffer to stop weight transfer. Standard springs are probably the best for traction but then you have the issue of roll. Camber is good for handling,but to much camber will actually give you less traction as the contact patch is less. First port of call has got to be tyres, stickier the better. Then i would look at roll bars for the rear,the stiffer you make the rear the less grip it has, which means the grip transfers to the front. But if you over do it your have lots of lift of oversteer and you might find yourself in a bush!

I am used to the look of the std ride height now, In the back of my mind i no its purposeful and it means you can run a lower brace without to much hassle, When I ran eibachs and a lower brace speed bumps etc just did my head in. I think the above set up with upper and lower braces and camber bolts is what i would do if i was starting again.

i have just found out why my fks are so bad they are 2 spring sizes wrong!
i have a set in jamies car which apparently were not bouncy but firm they had the 110 springs and werre his road and track set up and were fine
on the le theres coilovers front and eibach lowering springs rear with standard shock i was given a 100nm (not yet fitted)set of springs for the front which are the one up from the ones in it so no wonder the front is so bouncy its way off on spring rate!

ok i accept that.. but the ones set up properly with correct springs and bravo top mounts feel great but i have not had chance to drive it fast as only earlier been swapped over will try tomorrow and see what the difference is

the fks were on the le i bought from spee just fronts rear has eibach springs standard dampers but one is shot.. they bounced quite a bit but he gave me stronger springs to go in them which were 100s or so he said..but i have not yet fitted
the other car i have which is jamies old one with fk silverlines on have the 110 springs and correct top mounts and are a full set of 4 these seem to be firm but great cant say too much as havent yet tried them at speed or with all 4 on a car but i will as this is how they were meant to be and i have been making issue of bounce when i have not had them set up right and one is moving nerly an inch back and forth to the point where i can feel it when letting the clutch out ..so really its no way to test suspension

i cant really comment yet as upto now mine have wrong springs and one (front right) is broken so all i have said so far is realy not a fair reflection ..i am taking the car out again with the ones from the car i have with correct springs (which i bought as a none runner )
i know a lot of people have them and have no complaints that i am aware of ...jimbo feels they are underdamped and i see exactly what he means but i want to try them properly set up anyway thn i will know

They came with 80Nmm springs from FK, the 100's were sent out after complaints of them being dangerous.
Ecrab, if it was over damped, the 80Nmm springs would feel very hard with little movement, they didn't, they bounced and almost became a resonant bouncing where the front was pogoing down the road, that's under damped as the spring isn't being controlled.
The 100Nmm spring was sent out, this has a few effects, it changes the frequency of the bouncing, it totally over powers the damper, it reduces the comfort as you have little movement in the suspension. Can you push down on the slam panel and get any movement in the suspension ?
The Bravo top mount does add to the comfort of the FK's, I pinched the idea from KW as they use them and adaped the Bravo parts to fit with the FK's. I just feel the FK's are a bit of a bodge. They aren't adjustable for damping, you can only adjust the ride height and how many time do you honestly do that, once or twice at the most. So what's the point in them ? For the money you can get a good damper that isn't a compromise.
If you've go them already then fit the Bravo top mount and they ride ok with the 100Nmm springs, just too bouncy for me on uneven roads, they make you slower than a standard setup.

the bravo top mounts make a massive differene they feel much better than standard thats for sure ..the harder springs are not too bad after having the wrong ones in it certainly keeps the car flat cornering rather than bouncing.. its firm though but i would say they would be good on a track

jimbo i understand totally mate and what can i say except fair enough.. but if you are buying a set second hand for £300 or the like with the bravo mounts its not a bad ride and definately far better than standard for fast cornering and track daying..so at that money i would buy them over standard everytime...the fact they could be better is in no doubt and if i was spending the £600+ these cost new i would buy something else
