    Yes Motorsport Tech is where I ordered mine. Be careful using spacers with studs in them. They might be fine for cars and coffee but not for serious track us.

    That’s why I’m adding 3 1/2 APR studs. I never felt comfortable using the bolt on spacers.

    3-1/2 " studs? how thick is your spacers? I am getting 3" for the 50mm Spacers up front on the hub. Think that is too short?

    D35BF2BE-AC05-4E62-9ED1-5E5DF66F38D7.jpeg 1” spacers. APR says 3 1/2” studs are 1” longer than stock.

    Did you race karts ? That’s me.

    ARP advertises their studs as 1/2" longer than stock and 1" longer than stock. If you're putting a 1" (25mm) spacer on, you need studs that are 1" longer.

    Thanks JAJ. That makes perfect sense. Just need to find the parts number for the correct APR studs.

    BTW. I had a typo. I am not running 50mm spacers. They are 25mm for the 1" extension.

    I just wanted to thank you for the original post as I put the same wheels and spacers on my 350R - all works great!

    I did use 35 series Michelin super sports in the 305 width all around. Obviously it lifts the car up about 1/2” but it sure does drive better (tracks straight without the sticky tires) and has far less propensity to scrape the splitter.

    Lastly, I found the rear wheel/tire combo to be 8.6 lbs heavier than the stock R wheels. Most of that is tire I’m pretty sure.

    Thanks again for the thread.

    @snaproll welcome to TMO. The added height of the 35 series tires works well on the street. Are you keeping your CF wheels for track use?

    Yeah. If they are hanging on the wall, my wife can’t curb them!

    After taking the car to Sebring, and confirming its ass kicking ability, I probably won’t track it too much frankly. One race car is enough to support. But god bless these cars - they are fun. I definitely look forward to the move to S550 chassis.

    Rick. How is ur spacer holding up on track? I ordered a new set of wheel that requires to run 25mm spacer upfront. I am hearing mix stories of using spacers on track.

    I took Rick's advice and use the ARP studs. 7733 for front, 7732 for back and use 25mm(~ 1in) spacers for the front and it runs great on both the OEM and Aftermarket 6GR wheels on track. using 295/35-19 and 305/35-19 for OEM wheels and 305/30-19 on 6GFR wheels. No issues after two track days. just make sure you have the proper lugs and make sure torque it down at 150 ft/lb.

    Have fun
