    UN1 Rod Change Reverse Gear Lockout

    Having had a look around without any luck, does anyone know where i can get a reverse gear lockout plate/mechanism. Reverse on mine is left and back. I have seen the Tornado cable mechanism, but would rather a selector guide plate incorporating a reverse gear latch of some form. Any ideas?

    Graziano gearing - part two

    It's been about a year since I started offering drop gears for the Graziano (Graziano Gearing and Drop Gears) - multiple installs and feedback has been great from those who have driven cars with them installed. The one shortcoming of the 1.038 set, however, was the lack of a true overdrive gear...

    Top Gear

    GT 40 featured on Top Gear but without Clarkson slagging it off for being too small (as he did years ago!). OK probably a Superformance being presented as 66 winning car but still a good advert! Also has piece on Extra Gear with Jackie Oliver driving.

    Graziano Fluids Pre-filled?

    I went to add gear lube to my Graziano transaxle, and in opening the side access, fluid started to come out. Are these pre-loaded with gear lube? Should I drain what is in it and add new fluids? Does anyone know the amount of gear lube the Graziano takes? I have a tranny cooler. Do I need...

    Trans Ratio's

    Hi Gents I know there has been a lot of discussion around gear ratio's but I would like some feed back on what you think is the best final drive ratio for the street.

    UN1 gearbox

    Graziano Gearing and Drop Gears

    I put this post together to help others avoid the pitfalls I've encountered with my Graziano L140 - transaxle from the Ausdi R8, Lamborghini Gallardo and some others.

    016 third gear

    Hi guys, Have had the misfortune of knocking some teeth off third gear in my 016. If anyone has a damaged gearbox but with a good third gear please let me know. It is an AAZ ratio box with all the upgrades and has lasted well over the last 14 years behind a 347 windsor. As much as an...
