Will be running t34 on blues mate so around 380-390, can't ever see myself pushing it more than that with the amount of other cars I have.

Is it worth sticking a fresh set of rings in to see if that will take up some of the slack?

My vernier is fucked but managed to get rough measurements

No1- 91mm
No2- 91mm
No3- just over 91mm
No4- 91 mm

Il grab a better vernier and double check it tomorrow
