Front suspension geometry can be altered to improve road holding, further enhancing cornering ability. Standard Sprite and Midget settings from the factory are 3/4degree of positive camber, approximately 3 degrees of castor and 1/8" toe in. Stock spring rate is 271 lb/in.
The first and most often used step on both street and mild race cars is to replace all the rubber bushes with polyurethane; 88G274/POLY upper trunion bushes (4 per car) and 8G621/POLY A-arm inner bushes (8 per car). Just this simple upgrade will produce a much stiffer, tauter feel to the suspension.
The next alteration to improve handling is to add negative camber to the front. Simply lowering the car will increase the negative camber and thus all lowering should be done first. For road applications 1 degree negative camber is as much as is required. For mild street use, the simplest method to add a little negative camber is to raise the mounting points of the shocks. A few washers between the shock and the body does the trick.
For serious drivers exact camber can be achieved by the use of shocks with rose-jointed arms; C-GSA100L & C-GSA100R. These are really only suitable for race applications as the rose joints are not durable enough for high mileage.
