Caltracs and street

my 2 cents , you need a descent size tire, and a soft compound tire like e.t streets or similar, and you need weight transfer -adjustable shocks, you need to get that front end up quick to load the back tires, my et streets are a d-5 wich is the same compound of similar size drag slick. i recently added comptetion engineering adjustables on the front , i can tell it raises quite a bit faster than the summit adjustables, soon ill add adjustable rear shocks also, i heard there are better ones out there but these worked for my budjet.
