regardless of the rims, bettering a 60' by .2 will give about a .4 gain. the common school of thought is that for every .1 you drop your 60' you will drop your ET by .2......it does not always work out that perfect but it's about right.

yeah i see what you are saying, i was just wondering what you saw the gain from. i mean which combination to which other combination.

its a combination of better traction, less rotational mass, and smaller tire/wheel radius.

Street tires are street tires. You'll cut the same 60' times on all season crap tires as you will on $180 Toyo T1-S street tires. Dont waste your time drag racing on street tires or drag radials unless you are running in a class that specifically prohibits the use of slicks. If you want the best track times you must get slicks, period.

Guttermouf5150

alright, so do you know what size slicks to get for those wheels? 15 x 6? all i can find in slicks are strange sizes and i dont know what to get they are weird size systems or something. unless you know something i dont

just curious, why does that matter?

It matters for the gearing and the amount of power you will be putting down. Also what are your mods and your planned mods.

Guttermouf5150

well i've got a stillen intake, UDP, Stillen y-pipe, and apex'i muffler. id like to go turbo sometime in the future, but thats not for a while. also, i will be upgrading my clutch when i have my tranny rebuilt, which is not too far off. possibly a quaife(sp?)differential

So you dont have plans for an MEVI or JWT ECU? In that case I would get M&H Racemaster 6.0x26.0-15 size, so that you can run 3rd gear out instead of being forced to shift into 4th gear.

ok cool so there wont be any issues as far as rubbing or fitment or anything?

do you know about the slicks? do they require a burnout? is that a stupid question?

out of curiosity, if i did go MEVI or JWT ECU, what would i get then?

thanks for the help.

If you're shopping for that size also give Phoenix a call. They make that same size for a 6" rim and I'm curious if their pricing is similar to M&H.

MEVI/JWT is a combo meant for top end. With that, you could get away with a slightly smaller diameter wheel.


It is always a good idea to do a burnout in the waterbox at a track to get off of excess sand/grime on the tires to help for a better launch. Of course the extra heat in the tire helps as well.

On a straight line track, slicks will give almost as much benefit as a quaife for a fraction of the price.

On a straight line track, slicks will give FAR FAR FAR more benefit than a quaife ever will, at a fraction of the price of course

Here is a same day comparison of street tires, DR's and slicks with a 35 shot. Much spin with the street tires I just let it go so I was really slower than I run N/A which is a 14.6.

Street Tires = 15.1
DR's(Nitto 555's) 13.9
Slicks 13.2

The center of the Millenia wheels is easily dremeled to fit the rear hub if so desired.

Here is a weight comparison.

Stock 17's = 51 lbs
Millenia (cheap tire for rear) 29 lbs
Kosei K1's (slicks) 25 lbs

Almost a 100 lb difference between street and strip tire setup.

would you happen to have the 60' times and the trap speeds?

Jime

iTrader: (10)

Street Tires = 15.1 can't find that slip but I nailed it off the line so 60' was real bad.
DR's(Nitto 555's) = 13.9@101 2.201 60'
Slicks = 13.2@102 1.892 60'

Guttermouf5150

hey jime, what size slick do you run? i cant find the mag with you in it.

Jime

iTrader: (10)

M/T 22x8x15

D/R's were Nitto 555R's 205/45/15's

Both were same Dia 22"

This size is best for an auto imho, but manuals seem to do better with a taller 24-25" because of their lower gearing.

I shoulda bought the millenia wheels that u sold to Jer with the DR's.

Guttermouf5150

you can put that slick on a 6 inch wide rim?

btw, how much did you pay for them, if you dont mind me asking?

Jime

If you look back at my first post, I said I had the slicks on Kosei K1's, they are 15x7.

I tried putting the slicks on the Millenia wheels and even with over 100 psi they would not seat, even after retrying a few times with mega amounts of rim lube. So thats when I bought the Kosei K1's. Nealoc said he got slicks to mount on his Millenia rims but I am not sure what size the tires were.

My slicks were given to me by my Son when he bought his Talon (AWD) after he used them for 2 years on his VR6. I have raced on them also for 2 years so now they are going on the 2k2 for a 5th year of use.

They actually cost around $140 ea.

There is at least one slick that is made for a 6" rim, I believe its an M&H. Its also only 6" tread width which is probably ok for N/A. http://www.dragracetires.com/m_h.html
