It really depends on how much you are going to track the car.If you are Ed Sims and do many track days then go for it .If you use your car 90 % on the street and only do a few track days.Maybe the single adjustable (rebound and damping ) with no remote reservoir Penske T&A shocks may be a better option. If you have ever had adjustable 3 or 4 way shocks .It really takes a lot of trial and error to get them just right!And even than your not quite sure !! The remote res. requires a lot of attention as well You need a special gauge to check the pressures and a tank for the gas. You must also check the pressures before use .Temps and humidity effect the res.pressures.It also helps if you are an engineer!!
To me unless you are going to race or have a dedicated track car.The simple choice is single adjustable with no res.
