In my case if I am driving car 1, or anyone else for that matter who isnt used to ACT... car 1 loses. ACT is not easy to drive...I am still getting used to it and my 60' times right now arent what they used to be. I think it will all come with time and practice.
but its still
to be determined in my eye....
as far as fun factor goes...I CAN CHIRP THIRD...so thats always sweet!!!
I dont know if I would say to get the ACT unless you need a new clutch. Mine was slipping like a b!tch and ACT wasnt that much more than an OEM clutch so I went for it.
I'd say go for the UDP though. RVM and this other company are offering UDPs at decent prices. I am ordering one VERY soon.
