Well, the first track prep (and DD) mod has been purchased...
245/35ZR-19 Michelin Pilot Super Sport XL
275/30ZR-19 Michelin Pilot Super Sport XL
Some real meat with actual bump compliance will be nice on the street, too!
Other decisions are to run An Aquamist HFS-4 standalone for now, until I get my LSD since I will be traction limited...
And I will be springing for an OS Giken LSD most likely... $500 more is worth it IMO for the advantages in DD smoothness.
