What is your preferred bumpstop combo? 36/46 is popular with NB tophats. I'm thinking that 46/46 or 46/54 would be ideal with ISC top hats. Should the rear bumpstops engage at the same compression front and rear or should they engage on the front slightly sooner?

 

If you must, front first, understeer so you can see what you going to hit rather then oversteer where you cant see what you are going to hit.:-)
