Notes :
The C5 Corvette was one those cars that never gets old to look at 
I love the shape from the side, the curve of the hood, the short tailed rear end, the C5 just shows what a sexy woman can be in the form of a car 
This replica is a stock car complete with stock tires replicated.
The power of the C5 Z06 was originally 385 HP when it was 1st released in 2001. Then the car went some changes from 2002 model year, the LS6 engine was upgraded and it grows in power to 405HP with 400lb ft torque, a good increase that also paired with lower weight than the base C5. The test curb weight of the car during Car & Driver Test was 1418kg, this will be optional. I used the heaviest running order weight at 1474kg, about 3250lbs. Weight distribution is at 53.5 / 46.5 as tested by C&D, this is reflected in ballast position.
Suspension for C5 Z06 comes in FE4 Package, different than the FE3 Sports Suspension which was available for Z51 C5. The front transverse composite leaf spring is 525 lb/in in rate, similar to FE3 Z51. The rear transverse composite leaf spring is 714 lb/in, stiffer than the FE3 Z51 rate at 634 lb/in. The Damper and ARB has been setup to give neutral balance, with FE4 Sway Bars Package taken into consideration ( 31mm / 23.6mm ). My personal alignment is used, using the factory range as a base. I provided additional alignment setup, feel free to try them.
The C5 Z06 comes with limited slip differential ( GU6 ), I have used some preload and medium lock to simulate the LSD, this gives much needed traction and stability around Willow Springs ( Big Willow ).
The rear wing is optional, feel free to install it. I simply like the look of it.
The C5 Z06 was tested and tuned at Tsukuba, Silverstone GP, Willow Springs ( Big Willow and Streets ), Red Bull Ring and Laguna Seca. The main aim in this replica is to replicate the lap time at Big Willow that was done on stock factory tire - Goodyear Eagle F1 Supercar. This is comfort medium in GT6 The lap time was 1:30.6s on 4th lap by the legendary Corvette Race Driver, Andy Pilgrim. He also fitted Goodyear’s DOT-approved “S” compound version of the F1 and posted 1:28.3s on 3rd hotlap ( feel free to try replicate the time using comfort soft )
The real life race car driver of the C5-R Vette ( Andy Pilgrim ) pulled the magical lap on stock Z06 C5 on 4th lap with OEM Eagle F1 tire to prove his point to a motorcycle magazine that pitted the Z06 C5 against Suzuki GXR1000 - both were tested by Kevin Schwantz - a main feature article of the mag. The test run were heavily biased in favor of the bike and the Z06 C5 was driven with TC Competitive Mode enabled. The magical lap was close to 4 second quicker than the Schwantz manage to pull off. I managed to replicate the magic lap with the replica I think I had some slow section ( 2 corners were hairy 
) that could shaved another tenths or two at the very least.
Here is a quote from the letter sent by Andy Pilgrim to the Editor of the Magazine in 2003 :
I have included the replay of the "magical" Lap at 1:30.6s ( Big Willow ) on CM tire + personal alignment setup. Watch it and Enjoy 
ENJOY

For me, driving pleasure can be from driving replicas.
