I disagree with almost everything he has stated
. This is the attmpted quick fix that most people do to Cossies, and it just DOES NOT WORK
.
The reason why Cossies understeer is due to the REAR beam which has completely different roll centre to the front set up, suffers from horrendous bump steer and has no camber or toe adjustment.
The BEST thing you can do to any Cosworth is FIRST fit a 6° adjustable rear beam (either Zoo or Ahmed's). This will drastically remove a HUGE amount of the understeer. Once you have done that, THEN concentrate on optimising the geometry with adjustable front TCAs and if possible 3-door front hubs and knuckles.
I would not recommend compression struts on ANY road car, UNLESS you are retaing an anti-roll bar, because to remove this means you have to run massively heavy duty springs to prevent the roll. This then means the car is RUBBISH on anything other than a billiard smooth track (which means it will be SHIT at the 'Ring
).
I would personally keep the Konis (albeit have them on their hardest setting) and fit a set of Ahmed's springs, the rear beam and some adjustable TCAs. Optimise the geometry, relearn how the car drives and then if you feel it needs to be stiffer, the only way to do it is with a decent coil-over kit (NOT the cheap £500 option, as you're wasting your time), springs that aren't too hard (my car on softest setting is like Koni's on their hardest).
Obviously I can supply you with anything you need, but I don't think you should compromise in this area, so only sell things that I KNOW to work
.
The one thing I do agree on, is to fit the best tyres you can afford
