Not massively into modifying my car so put more money into maintenance and getting the most out of the standard car. Used to own a new MX5 before my HR Z, it had a lovely transmission so wanted the best out of the transmission on my Z. Going into 1st gear was very stiff and Knotchey so I decided to replace the grarbox oil with Redline MT85 (3litres) and whilst I was at it replaced LSD oil with Fuchs Titan Race Gear 90 (2litres). First few miles didn't really feel a difference but after a while changing up/down the box the shift is now extremely smooth and the stiff/Knotchey 1st gear has completely been gone !!! What a difference, makes driving it even more of a pleasure.
