They won't fit under a 2.5" spring.

I'm still a noob with Koni products, so I may not be the best person to give you advice on which inserts to choose, but I do know the 8611 are double adjustable, and better suited for track use. If you're looking for the 8611 insert that's dimensionally the same as the ones I have on the rear, its part # 8611-1262 Race (however, all the dimensions of 8611-1259 Race are the same...not sure what's different between the two).

Edit: If I would have actually read the catalog, I'd see that the 1262 insert is made for higher spring rates
Those were the special run back in the day. You would hav to have them revalved to match that spec. What is the front rate going to be?

They all have a flat head screw adjuster. The old Shigspeed setups had an allen key adjuster that fit into that slot. He used the same length insert in different length tubes.
