I wouldn't dissuade you from fitting "Coilovers" to a full race track car, but if it is also to be used on the road.......................stick to rubbers

what spring suit for fast road and track day?
What's the split? If it's more road biased, don't bother with coil-overs you'll be sacrificing a lot for little gain.

Surely there's no question at all about coil springs unless the car's only use is on smooth track tarmac ... and even then ...

makes no diifference as all the "kits" out there are not fit for purpose. you end up with a falling rate spring so you need to add ARBs to bring back some rising rate to the suspension. if it is a race car with correctly orientated springs than that is a different matter. and then you start out by weighing the corners so you can work out the rate you need.

Although I would agree that rubber cones would be best, you guys seem to be talking about cone replacement springs - not coil-overs as he has asked about.

NO WE AREN'T
The air would be blue, if we were talking about cone replacement springs.

The big problems with coil-overs are first of all, the springs are really for racing and are not the correct rising rate type for road use. A race spring has a very high initial rate to improve turn-in on a smooth track, but that is pretty useless on a normal road.
Secondly, the coil-overs mount on the dampers and the top damper mounting is not strong enough for such a configuration on a normal public road. It would need substantial modification to the top damper mounting area. Also, I have snapped a damper mounting pin on the top arm, and that is just with a SPAX damper on a rally car. How you could strengthen the pin to fit coil-overs and use the car on the road is anyone's guess.
Not something I would consider as the original rubber spring cone are absolutely right for the car.
But still vendors sell this coil-spring junk!

not at all. the replacement springs are even worse but for similar reasons and another big reason.
