We're anxiously awaiting the start of the new season with the new 987--hopefully the weather will break soon-- and just wanted to make sure I've got everything covered. Would appreciate opinions on the following.

Jack pad:
I used to have the link for the jack pad that fits the 986/987 jacking point with the center post that fits into the hole--anyone have it?

Digital Air pressure gauge:
my Longacre gauge that is at least 6 years old and last year was starting to give erratic readings; is there a battery in it that might need to be replaced?

New Helmet:
Our SA1995 Simpson open face needs to be replaced; any major differences between Simpson and Bell helmets?

Head socks:
Are they all made of Nomex? Just looking for something simple when I let somebody borrow my helmet.

Tires:
I bought an extra set of 987 18's with PS2's that we'll use for DE's; I've got a set of 17" Boxster style wheels that I've used for auto -x (7" F/8.5" R) and need to replace the VictoRacers. I've posted this before but am still on the fence. 245/45/17's all around or 225/45/17's on the front?

Paint protection at DE's:
I've seen where some people put clear plastic on the hood and fenders to avoid chips; what's a good source for this type of plastic sheet?

Thanks for any help with this
