Hey Guys- I'd like to add 19mm spacers to my rear(only) hub studs to bring my tires out just short of touching the inside of the wheel arch. Upon trying to install the spacers with my wheels( 18"x 10"- 65mm offset) I discovered that my existing(stock) studs were way too short. My current tires are 265/35- If I simply went with a 275 or 285 in the future, would they be significantly closer to the desired position? How difficult is the replacement procedure, what does it entail,& will it be worth the cost & effort for only the aditional 19mm(3/4")? I bought the genuine Porsche Spacers for about $30 for the set, and I believe the new studs will cost about $15. apiece. What size studs are recommended? Also- I understand that a minimum of nine full turns with the nuts is necessary for safety - could someone knowledgeable confirm this ? Thanks very much.

 

three choices:

1. pull the hubs and pop out the studs for longer ones
2. or, bolt on spacers (porsche OEM GTS spacers
3. proper offset wheels. I should have made my wheels incoprating the 17mm bolt on spacer i use 8" back spacing .

8.5" backspacing would have been better do this.

Buy the Porsche style spacers with the studs already attached. You'll be back on the road in 1/2 hour instead of two days trying to remove the spindles on the rear, pressing out the old studs and pressing in the new 10 studs.

yep and if you go the replace the studs method you have to figure in the cost of replacing both of the rear wheel bearings as the inner race that faces the wheel will come out with the hub when you remove the hub from the bearing, best choice is to get the spacers with bolts

 

Thanks Boys- I'm inclined to agree with you both. I'll go the route of the pre- installed stud/ spacers. That will be better anyway for track days when I'll use my old dishes& tires. Thanks again, Dave
