    Default Suspension for beginners

    Suspension

    It is arguably the most important modification. It won't matter how much power you are getting in your car if you can't control the car properly.

    Geometry tuning is also the cheapest mod too!

    It seems that a lot of CTRs have incorrect geometry settings which can make the car spin very easily. Get it checked using a proper 4 wheel alignment centre. 2 wheel is not enough.

    Some definitions:

    Caster angle - this is the angle of the steering axis tilt.

    Camber angle - this is vertical splay angle of the wheel.

    Toe angle - longitudinal splay of wheels.

    Unfortunately the CTR's suspension is not easily adjusted. Of all the above factors, only toe is adjustable. Camber can be adjusted with the use of camber bolts.

    There are no ideal settings - it all depends on your driving style and the roads you drive on. Satisfactory results can be obtained by altering the camber and toe.

    Camber dictates the vertical splay of the wheel. Negative camber means the bottom of the wheel pokes out. Positive camber causes the bottom of the wheel to tuck int.

    Negative camber improves the contact patch when cornering. Too much can reduce traction in a straight line and increase tyre wear at the inner shoulders.

    Toe angle describes the longitudinal angle of the wheel at its leading edge, closest to the front of the car.

    Toe-out splays the wheels outwards. At the front this helps to increase turn in sharpness but can make the front end more lively when cruising.

    Toe-in increases cruising stability and dulls turn-in.

    At the rear toe-out helps the car oversteer and reduces back end stability. Toe in increases stability. FWD tend to be setup with rear toe-in to stop snap oversteer.

    So armed with this knowledge you should be able to decide how you want your car setup. You'll just have to experiment. Remember that more extreme alignment setups will decrease tyre life.

    The majority of people go for the "fast road setup".

    The settings are:

    1 degree neg camber all round
    1mm toe in at rear
    1mm toe out at front

    Could pop over to TDi North in Warrington mate, aslong as the 18's aren't too wide then you'll have no issues with lowering it

    Thats almost the correct profile 225/35 is better but you will lower no probs with they tyres anyways mate. You should sort out the geometry if your planning to lower regardless of what size of alloys your running - your car will handle like a ba*tard if you get the fast road set up

    Yes. As has been said though, you could go for a more aggressive setup if you wished, depending on your driving style and how long you want your tyres to last.

    I have Tein springs and a fast road set up on my EP3, (done by TGM in Fleet,) and its well worth doing imo. You will need adjustable rear camber arms, (about £130 ish) as well as front camber bolts, (about £15,) plus cash for set up time at the going labour rate.
