Suspension

I need some advice on suspension and what to buy.

I have the Golf MK 3 and it will be a track car, I have to replace the suspension as the coilovers that are on it are knackered and are too low!

I have looked at a few different coilover systems and I thought I had my decision made, I was going to buy GAZ GHA coilovers, however today I have been told these will not be suitable for the track, they are more for fast road.

So I have a short list;

Take a punt on the GAZ GHA's http://www.larkspeed.com/index.pl?p=GAZGHA346&a=i

Or go more up market with GAZ GOLD http://www.larkspeed.com/index.pl?p=GAZGGA446&a=i

Finally I have also been recommended Eibach http://www.larkspeed.com/index.pl?a=i&p=18PSS65850030222∂=VW-Golf-Mk3-1-4-1-6-1-8-2-0-2-0-GTi-2-8-VR6-Eibach-Pro-Street-S-Coilovers

So, question is, what would you buy? and Why?
