Slowly building a 98 spec Boxster. Have done all the engine and basic safety features (cage, seats, restraints) what would be next option of the below
GT 3control arms
GT 3sway bars
PSS nine suspension ( currently has the ROW suspension )
Fire suppression
Third radiator - was at VIR this week and temps we're good without it
Anything else???

Here's my spreadsheet of all the possible parts/work one can do for a Spec Boxster.

I don't have an opinion of what specifically to do next, as most of this stuff is necessary for a legal and competitive SPB. My only advice is to prioritize safety and reliability over performance.

GT-3 lower control arms would be the next logical step. If you're getting a decent amount of seat time then you should be getting close to needing more neg camber to keep the front tires flat in the turns.

After that, its gonna be the whole BSR suspension package (PSS9's, adj sways, adj drop links and adj rear toe links). It is hard to do this one step at a time because all of the components work together (you need the PSS9's to lower the car and because the car is lower, then the drop links have to be adjustable and the rear toe link has to be adj.)

+1 I don't run BSR but I do track extensively. Do this all together, you'll be disappointed in the results doing it peace meal.
