I just added 5mm spacers to my is350. however i can only get 4 rotations on my lug nuts. I would like to buy some extended ones. where can i buy some, and how long should they be? thanks

 

ARP IS300 extended wheel studs I've read should work on the 2IS. They will be plenty for your needs. You might need open end lug nuts though.

 

well i definitely don't want to have open ended lug nuts, so I just need some studs that are like 5mm longer. anyone know how long the stock ones are?

 

since its on the same topic,
how hard is it to pop the oem studs out? (never done it before) just a little hammering?

 

Going out is easy
Pulling them through can be tough at times.
If your impact isnt strong enough then you will have to get them pressed in.
Pressed in personally is better, but that requires alot more dissassembly to get to that point.
We recommend the ARP ones to all of our 1000+WHP cars. I personally have used cheaper ones
on a stock SC300 and had them break only torquing the lug nuts to 79 ft/lbs, so I switched out to ARP's as well.

 

just went on ebay and saw some ichiba studs, any good?
