I'ev been searching for the last half an hour, been on the phone with Summit, and can't seem to get a confirmation on the part# for ARP wheels studsfor a 2001 GS430.

I bought the ones from Ichiba (50mm length) and something is seriously wrong as the damn splines just won't go in... They are too thick for the wheel hub.

Anyone have a solution?

Thanks,

Anyone por favor?

 

Did you search..Cause the information is there

 

I did and found ARP#1007715 for an IS300.

I believe they are the same a our GS300/400/430 but cannot confirm. ARP offered help.

Thats it....ARP#1007715

i have the ichiba studs that came with the 10mm spacer package and they worked fine

 

Bumping an old thread.

Anyone else buy extended studs from other reputable brands? I was about to buy some for $20 off amazon, but somethings telling me not to lol. Can you post how much and where you got them from?

 

just buy the arp or ichiba, DO NOT BUY SOME OFF BRAND. these are the only thing holding your wheels on
