Hi Andrew,

Below is a good starting point. Keep in mind, the baseline for the CQ31 is also the same as Q31 (the C just notes the kart may have originally come with front brakes).

Q31 X was produced in 2000 as Garry mentioned in a previous post.
- spindles in the middle (one spacer on top, one on bottom)
- 75mm front hubs set with two thick and one thin spacer on the inside which should leave you with one thick and two thin on the out side
- 1.5 degree caster
- camber at 2mm positive and 2mm toe out
- You may have to turn the eccentric bushings slightly to create the 2mm of positive camber which will decrease the caster angle a bit, but, don't worry about that
- If you find that you need a bit more caster than you can add a second eccentric bushing
- Front bar in, F3.0 axle with 100mm rear hubs set 23.5 cm from bearing to the outside edge of the hub
- Seat should be at 59.5cm from the front rail to the front edge of the seat on the left side and 60.5cm on the right side
-Top of the axle to top edge of the seat 23cm if you are using a 40mm axle (which was standard in '00) and the bottom of the seat should be 5mm below the frame rails
- Start with one seat of seat stays on each side. Lower crash bar on the rear should be loose to begin with
