Must have been a kicka$$ website! Lol just kidding. +1 Man cant wait to hear how you like them.

By the way, I wanted to ask: As far as reclibrating the speedo, can that be done at any mechanic or does it have to be a speed shop/dealership?

I know I can get a tuner to do it myself, just don't have the money to get one. For the time being just wanted to find out what kind of shops can do it for me.

A litle cheaper alternative is the speedcal box. But this ratio has to be changed with a tuner or the speed-cal.

Gear swap is now complete. Starting break in now... luckily they were used so only breaking in around 100 miles. under light acceleration they already feel better!

Was able to get on it for a short period today in 2nd and 3rd. Felt very good and pulled a lot harder than stock for sure. cant wait to do like a 0-60 or 0-80 pull.
