Classic line insurance is the one I use.
6 non PCGB track days included and then you buy more if needed.
All PCGB trackdays covered
I think they were pretty reasonable on price also when I used them in September
good luck
Ed, I didn't bother changing mine back. OPC didn't even notice. They only commented on how much of a good idea the Zunsports were, but no comment on the GTS diffuser
John, drop me a message with where you will be and I'll do my best to drop by. Im staying near my office on the west side of Houston near the I-10 towards San Antonio. I've never been but I hear it's nice and the river walk is cool. Enjoy the race and Texas.
Ed
Looks great, good to read that you have plenty of experience removing the bumper now . I must confess that this method seems a far better way of changing the diffuser than leaving the bumper in situ as I did and trying to change it whilst underneath the car in very tight space.
If I ever decide to put the old ones back, then I shall be following your approach.
Cheers & great job
Tony
