I've just installed a set of BC n+ for my Teg VTIR. I'm going to track my car at Wakefield and want to get some advice as to what specs i should set for my coilovers for optimal handling. thanks in advance.

you've opened pandora's box :P

All things go into consideration when determining optimal ride height and damper stiffness. for example, wheel size, tyres used, tyre pressure, car weight, other sussy components such as sway bars, and last but not least, ur own personal driving style. when it comes to track, its all trial and error. go for a run, come into the pits and adjust where you see fit. go back out and see if your corrections made a difference.

there's a common mis-conception that running at full stiffness is optimal or the lower you are, the better your center of gravity - this holds true only to a certain point which again, varies from car to car.

yep all trial and error

also remember body roll isn't necessarily bad :)

yup its totally relevant to your car and driving ability and personal preference.

But too low is a BAD thing for wakefield.

A general guide to Race car set-up goes like this.
Set the ride height, taking into consideration the avaliable bump(compression) travel as well as the jounce(rebound).You don't want to get the thing into the bump stops at all under "normal" driving.
While you are considering the ride height look at your muffler and anything else that is within 3" of the ground, ask yourself can you afford to lose that part from the underside of the car? Lower the car based on your answer....
Second thing to consider is roll centre and bump steer, these are tied to ride height. Go too far beond having the lower control arm parallel to the ground at ride height and you will get an unusual amount of body roll as well as steering that seems to jerk and wander over bumps.
Once you have your chosen ride height, you then select spring rates that are stiff enough to keep the car out of the bump stops and not so stiff as the chassis skips over bumps and under brakes.
Match the Dampers to the selected spring rate.
Wheel alignment to suit the camber curve generated by the suspensions arc of travel.
Fine tune your corner entry with toe adjustments.
Sway bars will look after your mid corner chassis roll.
A very general set up regime, but one that should bring some order to the "madness";)

IF you are wanting to track seriously I would of went with something with camber adjustment plates which the N+ dont come with.

DC2 coilovers don't come with camber adjustment plates, they use camber arms which are bought seperately..

yeh pretty sure camber top mounts don't do anything on a dc2 as its different sussy geometry, you need to get the camber arms to change the camber settings.
