It seems that replica kit cars such as the Lamborghini Diablo, Ferrari 355, and Ferrari 512 Testarossa are gaining popularity at an alarming rate. The original versions of these cars use fairly flush faced wheels with negative off-set. This type of wheel leaves more room between the wheel mounting surface and the vehicle chassis, allowing the engineers to perform better magic with the suspension geometry. In general, the longer the suspension links, the better the suspension geometry. When the Fiero based clones try to duplicate this wide stance they are faced usually with two options, neither of which is ideal. The first option is the use of rims with lots of negative off-set to fill up the wheel opening. There are two things wrong with this. First, the wheels do not look original and second, too much off-set is detrimental to wheel bearing longevity. The second option is the use of wheel spacers. Thin wheel spacers can usually be used without creating too much trouble but some of the track increase requirements mean using spacers which are dangerous. Front wheel spacers and off-sets always modify the steering geometry by increasing the scrub radius which affects performance and usually creates tire/fender interference.

The third and most sensible option is to install longer suspension links similar to the original Ferrari , Lamborghini etc. Our wide track kits for the front and rear suspension include longer control arms and convert the existing suspension to the coil-over adjustable type. This allows the use of standard off-set, original looking wheels safely and actually improves the suspension geometry at the same time. The rear kit includes strut relocation hardware to correctly position the struts.

We can supply kits to widen the front track by up to 6" and the rear track by up to 8". It is important to note that when widening the rear suspension, the original Fiero axles will be too short. Also when the rear struts are located further outboard, a new strut shaft access hole will need to be drilled in the top of the strut tower. The new strut hats supplied can be used as templates for this purpose. In some cases depending on engine / transaxle combination, when increasing the track width, only the short axle needs to be replaced as the existing long axle can be used in its place. We can supply longer axles for other increases. There may also be a problem with the brake flex hoses. We can help here with braided Teflon hoses and fittings.
