Just to add Steve, it's not unusual for the drivers side mainspring to settle to a greater degree especially if car is driven solo. From memory the drivers side required at least another 5mm of thread showing above adjusting collar to reduce rebound spring clearance to zero static.
Another issue is that due to kingpin geometry the drop test recommended by SSL, even with shocks removed, can fail to provide any significant bounce because the tyres are forced outwards as suspension compresses, compromising same. This effect is exaggerated by wider tyres on Roadsters for example. You have therefore to resort to a little cunning as mentioned by Doug a few posts above, and obviously with freshly greased and ideally well run in stub axle bushes, to gain a median for the static position each side.
The 'bounce' you encounter is probably from the side with 10mm of play static. This allows excessive rebound suspension travel. Correctly adjusted (you will need the two C spanners supplied with SSL kit) the total suspension travel over a bump will reduce but in so doing allow a more comfortable ride due to reduced bounce as well as roll. Dampers can then be adjusted to compliment.
