what would be a good size slick or dr for the track and what rim should i use??

 

You're gonna get 1000 different answers cuz everyone has their own opinion on which is better. Best of luck tho

 

I say if you can trap in third on a stock size tire run a 24.5 m and h slick. Or a 225/40 stock size dr if you can find one.

 

i have a pair of nitto n1's stock tire size could i use those?

 

16" wheel is the easiest to use and will give you an "OKAY" selection of slicks.

15" wheel is ideal but you have to grind down the brake caliper a big to get it to fit. But if you can get a 15" wheel, you'll have a very wide selection of tires.

Figuring out what overall size to use depends on your setup. How much power you make? What trap speed are you at? What gear you want to finish in?

Our cobalts are geared very similar to an old GM 3 speed auto. Only we got 2 extra overdrive gears on top of that for gas mileage.

 

With the stock size tires (25.7" tall) and a 7500rpm rev limit, 3rd gear ends at 120mph.

With your modifications, I seriously doubt you are anywhere close to 120mph.

A 24.5" tall tire would put you at 114mph through the traps. That's still above what you probably trap. I doubt you are at 110mph.

If you dropped all the way down to a 23" tall tire, that would put you at roughly 107mph through the traps in 3rd gear. I wouldn't drop any lower than that because you are probably going to pick up a couple mph from the more aggressive gearing.

You can find a 23" tall tire for a 15" rim here..... M&H MHR-21 M&H Racemaster Drag Slicks

That may be too small of a diameter though. The next size up is a 24.5" which like I said above, would put you at roughly 114mph, but if that's the best you can do, then there it is. At least you would leave yourself a little more room for more power.

If you need it on a 16" rim, then here is the best you can do, 16" rim, 24.9" tall tire, will put you at 116mph roughly through the traps..... Hoosier 17320 Hoosier D.O.T. Drag Radials

ralliartist is the man help me wit my slick ..

 

subd thanks ralliartist

 

No problem.

 

im going to run a 26" tall this year.

my problem are my rims dont have enough back spacing for me. mine have 4.5 or 4.75" of backspacing...

if you are buying drag rims, stock backspacing is 5.43" on a 7.5 inch rim.
if you are like me running a 10inch tire on a 8.5" rim youll need comprimise either with a 5 inch backspace. or a 5.5 with a decent spacer.

because of my spacers i need 6.5 inches of backspacing to run a 10" tire.

still looking for a deal. lol

 

my new 24'' on 15'' rims
i hope get into 13s'

for 141 whp it ll be often i guess

 

You should definitely make 13's based on the times in your sig Huck

So Ralli... What do I want for trapping 133? Oh wait my gearing is different, crap

 

133? lol, at that point throw the gearing calculating out the window. Put you at least a 10.5" tire on it and go to town!

 

24.5" is really the largest you want to run, a 26" tire will hurt your gearing.

The gearing the F35 or F23 is bad enough from the factory no point making it worse.

A 24.5" tire will stick 600-700whp, no need to run a 26".

The smallest wheel you can run the better, the more sidewall you have the better off you will be.

M&H is your best bet for drag slicks. Its been said many times that they are much more suited for a FWD car than a MT tire is, this is why all the Honda guys run on M&H.

 

Eventually I'm gonna buy a drag set up for this car and take her to the track. I'd like to go to a big CSS track day in Ohio or something though. cmiller seems like a cool guy to hit the track with.

 

what track do u run at?

 

I say we try to get something together. Or Milan is about an hour and a half from here. That's an option.

 

Only been to Lapeer with this car. It's not the best track in the world...

Milan's about a hour and a half from my house too. Wednesday's are usually a good day to go since not too many ppl go. NO E.T.'s are packed though.

 

Milan is about an hour and 15 mins from my house so yea we should all go there one wed when spring comes.

I hurd Lapeer sucks
I race at martin (131 speedway)

 

pshhh eff all that mess, I race at Norwalk

cant beat a track that is on both NHRA Full Throttle circuit and the other one that runs top alcohol.

 

Sounds like a plan. Im trying to find a good trans person to put my cryoed trans together when it comes back. 4.45 final drive

 

This is my next thing for sure. pwerks is working on getting somethings inline. I wonder how much it would help putting in just the 4.45.

 

I will let you know as soon as spring comes and race season starts

 

i need ideas for rims.... anyone? anyone?
