The following settings are intended as a good starting
point for getting your car setup correctly. Do not deviate too much from these
settings and dimensions as it may lead to instability in your car. Information
is provided in good faith and have been tested under track conditions. SSC and
Club Stylus cannot accept any responsibility for any losses due to loss of
control of a vehicle either on the road or track. Please remember, track and
road conditions can vary immensely and significantly less grip is available in
poor conditions such as rain.
Ensure you are getting at least 50mm of suspension travel. SSC can supply
various angles of rocking arms to lower the car and also provide long travel
suspension (Developed for road rallies and bumpy Welsh roads). Simply lowering
the car on the spring platforms may allow the car to bottom the suspension,
giving rise to instability at speed.
- Rear Suspension Movement. Ensure there
is free movement of the suspension. This is done by jacking the car up on axle
stands under the chassis, removing the spring and ensuring there is easy
movement from the bottom of travel to full bump travel. If the suspension is
tight, remove the suspension arms and ensure the polyurethane bushes do not
sit proud of the steel insert. The steel bush should sit proud of the bush by
0.25mm to 0.5mm each side.
- Reduced Roll Stiffness. If you are
after reduced roll stiffness at the rear, metalastic rubber inserts cab be
used in the rear trailing arms as a replacement for the polyurethane ones.
- Damper Settings. Set 'SPAX' to 7 and 'GAZ'
/ 'AVO' to 8 or 9. Post October 2003 cars (225lb front and 170lb rear springs)
set 'GAZ' to 7, set 'Protec' on the bottom of the 3rd damper range (Call SSC
for instructions on how to do this).
- Tyre Pressures. Set tyre pressure at 20
to 22 psi. (Depends on personal feel and car weight).
- Watts Linkage (De-Deon). If you have
De-Deon rear suspension, also ensure the Watts linkage is free and also has
the required bush clearances. It is also adviseable to use a copper slip
grease to lubricate the suspension bushes.
- De-Deon Rear Toe-in. Set the rear
toe-in at 0 to 0.2 degrees toe-in, equating to roughly 0mm to 1mm difference
from front to rear of a 14" rim. Camber should be set to 0.5 degrees negative.
- Front Suspension. Ensure that the front
suspension is moving freely, set the camber at 1 to 1.5 degrees negative. If
you have adjustable bottom arms set the castor by turning the steering wheel
to one turn (approximately 20 degrees at the wheels) and set the corner's
outside wheel to 3.5 degrees negative.
- Tyres. For best grip, try not to use
tyres older than 2 years and make sure they are in good condition (the older
the tyre the harder the rubber and the less grip you get). Recommended are
Yokohama A-539 or Falken ZE502 for road use. Make sure tyre is at least has a
speed rating of 'H'. For track use fit AVON ACB10 or Yokohama AO32-R tyres
(Make sure your sump is adequately baffled or you will get oil surge due to
increased cornering forces with these tyres).
- Spring Strengths. Opt for 220 - 230
lbs/Inch springs at the front and 180 - 200 lbs/Inch at the rear. V8 cars
should look at 220 - 250 for the front springs.
- Anti Roll Bars. Fit an anti-roll bar,
this should reduce the likelihood of the inside rear wheel lifting on hard
cornering and increases the traction out of corners. Road cars generally do
not require anti-roll bars.
