anyone know if the standard '02 996 C2 wheel bolts are 45mm in length?
I'm looking to purchase new ones and can't seem to find an absolute reference.

 

Yes, standard wheel bolts are 45mm in (thread) length!

Nikos.

 

new lugs are the same thread lengths but the heads are much sleaker. less unsprung weight. lol. I bought a set, makes mad power.

 

good for at least 15rwhp right??

So the shank length (threaded section) on the OEM bolt is 30mm. The overall length measuring from below the nut flange is 45mm.
That's the word from Porsche.

Anyone who is running 19" 997 OEM Carrera wheels on a 996- Can you go 15mm spacers all around or just 15mm in front and say 5mm in rear?

 

Im 15 in the rear 5 int he front with 18s...Dunno about 19's tho

 

15mm rear / 5mm front?
that sounds backwards- at least, looking at my car presently with the 5-spoke 18's I have more inset on the fronts than I do on the rears.

I guess it's different depending on type of rims?

 

I have after market rims now...
