Latest tweaks to my Z06
Discussion
Had to wait a few painful weeks whilst various parts arrived, but I'm finally back in the driver's seat of my Z06 and boy is it great!
Firstly, Ian Goss did his usual great job, fitting a new windscreen to replace the original which had a massive crack in it for ages.
Then he fitted the full width rear spoiler I brought over from the States in the New Year:
I think it looks great and it generates more downforce than the stock stubby one.
He also refitted my throttle body and intake manifold after Lingenfelter ported them for me.
Russell then kindly fitted my new Lingenfelter fuel rail covers:
Ian then delivered the car to my race workshop, Autofficina, who are just round the corner from him in Surbiton.
No pics yet of what they did, because it consisted of front race wheel bearings and LG Motorsports spindle ducts and brake hosing which is tricky to see unless the car is up on a ramp.
Finally I fitted the new LS7 "427" badges that I bought in the States:
Surprisingly, even before a retune, the ported TB and intake do seem to have made a noticeable difference to the power delivery with massive, smooth power available right through the rev range.
It is a rocket!
Just a final dyno session and remap now and I'm done. Probably...

Brilliant looking & mechanically modified car David. Incidentally, I thought your write up between the engines of the F430 v ZO6 made excellent reading and just shows how right GM are to carry on with what the European manufacturers would probably (in fact guaranteed) refer to as an out of date design.

They are 18" all round. I think 10.5" front, 12.5" rear, 285/30 and 335/30 tyres.
One of the reasons the ZR1 will be too expensive to run as a track day car is the lack of 19" front and 20" rear track tyres and you won't be able to swap for smaller due to the massive brake discs.
Given the standard Z06's iron brakes and standard pads presumably they are costly for track days whereas the ZR1 has carbon / ceramic brakes which are going to be pretty much unbreakable.....as for track day tyres....I have no doubt that someone will be along soon with a suitably sized tyre for the ZR1 wheel sizes....also the Z06's are getting to be seriously cheap in the US so having one as a purely track day car would also be an option for the potential ZR1 owner should they be so inclined.One of the reasons the ZR1 will be too expensive to run as a track day car is the lack of 19" front and 20" rear track tyres and you won't be able to swap for smaller due to the massive brake discs.
Michelin are only just beginning to make Sport Cup track tyres in the 325/30 19 rear Z06 size and that is because the Porsche GT2 also now uses that size.
It will never be economically viable for them or anyone else to make 20" track tyres IMHO.
IRONically, hard track use is the one place CCM brakes do wear out quickly/crack as any GT3/GT2/Enzo owner will tell you! And then it is £10k+ to replace all four discs...
There are now several, fairly cheap aftermarket calipers available for the Z06 so you can ditch those 6 thin padlets.
My 14" Brembo GTs were not cheap, but they are fantastic! Replacement friction rings are not too expensive and pads are cheap.
Even Chevy have pegged the Z06 as the ultimate road-legal track day Vette due to its light weight and NA engine whereas the ZR1 is the ultimate road going supercar-slayer.
If I lived in the States and could get a ZR1 for list, I would.
Over here, I fear they are going to depreciate horrendously, like the original ZR1.

What were the terminals on the Z06 at V-MAX?.
Just did a search: 188mph and beaten only by three highly tuned 911s, including the ludicrous 9FF Cabriolet! http://www.pistonheads.com/gassing/topic.asp?h=0&a...Only got one run due to the deflating tyre.
Will definitely go back once the remap has been done.
