Just bought a set of those ugly *** 16x7" clk wheels lol. Now i need a set of dot legal tires. I read that one of the guys is running 225/50/16's. Is this the biggest we can go on these? Am i going to need spacers also? Getting proper size lugbolts wont be an issue. Any input is appreciated. looking at hoosier dot drag radials P225/50R16 213$ . Anyone running the P255/50R16 they are wider and 26" tall vs 25". I definitely dont want rubbing with these softies.

You can run the 255s but not if you are lowered. I know someone ran the 255s but the suspension needs to come up a little.

You need to run them with 20mm spacers. Get the H&R DRA spacers, the spacer bolt to the hub and wheels bolt to the spacers, that way you don't need longer bolts, can can use the OEM lugs.

Wheels also need to be drilled to 14mm as I think they come 12mm, very easy to do.

Lastly you need to trim the rear brake pads, need to cut off the little tab that is used to pull the brake pads out. When I get to a PC I will post pictures for you of what needs to be done or someone else can chime in before then.

Happy drag racing.

awesome, thanks for all the input. My wife is hoping to run it at import face off this year. Although it has to run in the forced induction pro class, since these events werent really intended for big v8's with blower lol. The forced induction sport class only allow n/a 8/10/12 cylinder cars? wtf is that? Hopefully all the other little imports will break down . Id love to see an n/a c63 come wipe that class up too. Anyone in dfw want to come out. its november 9th at ennis

drilling to 14mm is no biggie. I have a set of spacers laying around, ill have to look at what size. Any idea on the center bore size?

Wow, sounds like a lot of work to make drag wheels/tires work on our cars.

Here u go road

You need to trim the little tabs otherwise they will rub

And follow charlie's instructions

I know what you mean. I wanted to call up Weld Racing for something a little more sexy.

Not at all, sounds like a lot but 5 minutes of work.

The spacers are under $100, drilling the wheels is simple, same holes just increase the thread size. Cutting the brake pad is simple, just take the pad out and use some tinsnips or something similar.

You can also use rim screws to stop the rubber turning on the rim but I got a 1.59 60ft without it.

As for the centrebore it is the same as the C63, 66.6 so you have right there.

thanks for all the help. I know i've seen that other thread just couldnt find that exact one for some reason. I'll be sure to post pics and results of the next track visit.

225 s kinda small don't you think

roadtalontsi

ya, i do think they are small, but the problems with the other dot tire choices is they are 26" tall and wider. I dont want any rubbing issues. Considering im lowered and even with the adjusters up 26" tall tire with any real width can rub easily. Ill be running these tires at lower pressures so they'll probably bulge a little. What are you running? There arent many posts with any helpful info. I just went with the confirmed size someone else is using with this setup.

225s are a little small but they are sticky enough.

I am also running a Weistec Stage 2 blower, and the 225s did their job.

Ran 10.7s and 10.8s all day, with low 1.6 60fts each time, and one run was even 1.5x 60ft (can't remember exactly but it was either 1.58 or 1.59).

Im running 17s with hooiser dot drag 275/40/17.

They are also for sale with new tires with 4 easy passes on them.

She ran 4 times, I ran once - the faster time
Car was hooking up crazy good, i know i could've launched it a little harder too.
We were competing at import face off, which the class rules are a joke. We were forced to enter the forced induction PRO class. The forced induction sport class only allows n/a 8/10/12 cylinder engines lol. because n/a is forced induction... So our car was the only one of 6 that is daily driver, drove to the track not trailored, full unmodified interior, a/c etc... Having said that She lost the first round to a 8.6 @160mph supra lol, with a 76mm turbo, nitrous, powerglide, gutted interior and a parachute haha.

Good work mate. Where are you located? The 60ft looks decent but DA must being hurting you.

roadtalontsi

Dallas texas. It was actually a beautiful day. Weather could not have been better. I wanted to put some race gas in to get all the timing but they ran out of all the unleaded . I also dont have the trunk ice box tank either. Our pump gas has been rather crappy lately which doesnt help at all.
I didnt check the DA for that particular day. but ennis 1/4mi is only about 500ft above sea level.
