Very easy to adjust the front - you just yank the tray in and out. Its spring loaded. Goes for $1,200 from bekkers, Turners,etc. I've thought about getting the lightweight rear wing, are you going through racepad.com for it? I think if you get the rear, you should get the front splitter too. Where is the best place to get one of those? How difficult is it to adjust the front? And how difficult is it to add and remove the rear inserts? Inquiring minds want to know!
