The items i have changed are the shock towers for carbon fibre items with the front having the much needed bridge for strength, associated plastic servo mounts. Also the pistons in the option house shocks for modern lazer mk5 items (w5181-03 piston set). I am using lipo saddles 5600mah 95c and brushless 6.5t hpi motor 100t spur with 23t pinion.
Before i put my pride and joy up against the new cars i thought i would ask for the knowledge from the expert vintage lazer racers.....
is the manual a good starting point for a set up of the car?
What shock oil/pistons and lb springs to use front and rear?
Will the slipper be up to the job with a 6.5t brushless?
Any weak areas for the car to watch for?
The track surfaces i will be racing on are a hard rubber floor(indoor running track) , also a mixture of carpet/polished floor.

I think your going to snap the belt. Also you should be posting this on the main Lazer thread. Im designing a belt tensioner block to be attached to the gearbox but youll need to cut a section away to do it. Also slipper may not be up to the job either but with a tensioner fitted you can tighten the slipper. Tyres yellow mini pin work fine, gear ratio well id opt to start with a 23 and go up or down considering. Id go for less accelaration more top end to save the belt but would rather you used an 8.5 with the standard gearbox
Set up, well i used traxxas shocks but if you use kyosho shock seals and use three holes front 2 rear you could try 50 front 30 rear with schumacher grey front and schumacher white rear. May also try size 2 all round 35 frt 30 rear.
