I'm not sure if they do as standard but mine had one as it fell off. It was knackered so could have been 12 years old quite easilyI've heard mixed reviews re alu under trays. Unnecessary expensive and liable to grounding. No personal experience.
Does the GT 3.2 come with an undertray? Mine doesn't have one.
You will when you ground it hard .. my Ali tray took the impact ... the original fibre one would have gone "Nah!" and my sump would have taken the force. That was a large trolley castor .. the type used to re-stock shop!!! Took ages to know the tray back out. Plus they look better, are easier to fit, and stay put!For the cost of them I just don't see it as value. When you can buy a plastic one so cheap. My 156 has original under tray, 17 years old. The screw hole broke so now attached on one side by a cable tie. Works fine. The plastic has got to be lighter than alu and how often do you plan on grounding it anyway? The alu tray won't offer any realistic protection to your sump etc.

Had one on my Spider, really well made :thumbup:
I'll go along with that. Being lowered I feel safer knowing a scrape over a speed bump is only the tray.had my alu tray fitted both to the jts and the 3.2. Highly recomended. Bonus is better clearence underneath, but it can rattle a bit. Definately better protection than the crappy original.
