I'm pretty sure the valving on my Tcklines allow me to go to 650/700 which would be alright for me.
Since I'm new to most of this.
So I might be best getting some stiffer springs for the Tcklines, and put them on the track car.
I'm pretty sure they can be rebuilt.
I go to Shannonville, TMP, Mosport DDT, and we will be new to Mosport GP soon.
