I bought some Kosei TS wheels from Tire Rack. I didn’t realize it at the time I purchased but they use a lug nut that this very slender and requires a tool they provided. It does not use a typical socket. Had I known that I would have waited for the K1's to come back in stock.

I would like to install extended lugs so I can use a spacer on a different set of wheels. The lug nuts on the Kosei's are not are not open ended so an extended lug will not work.

Is there a different nut I can use or should I just cut the closed end of the nut off?

 

lots of people make narrow "tuner" style open ended lug nuts.

 

Get a set of 17MM lugnuts. Thats what i used on those wheels.

I used McGard Splinedrive on mine.

 

Funny story about McGard. I figured heck if I go to their headquarters and factory the lug nuts and seat locks will be real cheap right? After sitting down and talking about the seat locks and such I got the prices. Literally triple what they are online, and the girl said to me you are better off ordering them from like Jegs or Summit lmao. And the seat locks were bought out by an S2000 owner and you need to submit him like a copy of your title and pictures to verify you own an S2000 so you aren't just buying the locks to get a key to steal S2K seats. Well what if I have seats worth more than S2K seats and what to protect them? lol
