PO also installed longer lug bolts, but I'm looking to add another 5mm spacer on the rear and convert to lug studs to make wheel swaps easier and to make sure I have plenty of thread engagement for upcoming HPDE & AutoX season.

I use these on my spb with no issues, and a good price point.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 2004 Boxster S came with 996 series Carrera wheels and ECS Tuning spacers already on it to accommodate the offset. PO also installed longer lug bolts, but I'm looking to add another 5mm spacer on the rear and convert to lug studs to make wheel swaps easier and to make sure I have plenty of thread engagement for upcoming HPDE & AutoX season.
For those who have done the lug stud conversion, where did you source your parts? I'm looking at Elephant Racing's 5mm spacer shims to go behind the 15mm hubcentric ECS spacers, and I think I need 70mm studs for the rear. Probably need 60-65mm studs for the front.
Grateful for recommendations.
Cheers,
Matt
tarett or rennline. they also sell some nice, light (expensive) spacers. pelican even. you may find that it's the same product sold by all three vendors - they tend to share.
I got mine at ECS Tuning. Excellent quality and the best prices I could find. After that, I bought some eBay spacers, and they are terrible quality compared to the ECS spacers.
I like the design of the tarret pieces. I am not sure they will look good though. They incorporate a shoulder which buts up against the rotor hat surface thereby removing a fair amount of the stress concentration that would normally be resolved at the hub thread and stud interface. Less bending stress means a lower probability stud failures.
There is also less direct stress on hub threads as the stud is not jammed into the threads on installation.
I have not used them as yet and wonder about wheel lug hole clearance around these shoulders.
I believe one could polish the bullet nose area of the studs to a gunmetal colour to better match wheels and nuts.
is the fact that they would put extra load on the wheel bearings, and those even if they are not too expensive to buy, they are a pain to replace.. :-(
What ever ones you buy I strongly suggest the type with the bullet tips

These came from Rennline I believe they were 45 MM
Are you planning to stack spacers? If so, I suggest getting a single spacer at the width that you want. One less failure point (wheel->spacer flange->hub vs. wheel->spacer flange->spacer flange->hub). I know H&R makes 20mm+ widths and likely others do too.
