just wondering about a few things before i buy one,
Am looking at the champ pack.
How many of you have bought secondhand and cars been ok?
Can you buy the friont carbon shock tower easy is it available anywhere?
front wishbones sound fragile, is that due to the driver or is that a area that can be strenghtened?
The car am looking at has upgraded bearings and titanium screw set....
