What Tires To Drag Race On?

[dyefuker]

hey im prity sure i know the answer to this one but just curious on everyone elses opinions

i have 18inch rims, wich are 9.5inch wide on the rear with maxxis 265/35/18 tyres on them

or i can go with stockies on the rear which are the standard 225/50/16's which again are the maxxis brand and have alot of tred

what would be the best to drag on at heathcote?

last time i ran at calder park i used a set of 205 semi slicks and did a 13.58 quarter mile pass with perfect launch and all gear shifts right on

my r33 s2's mods are quite basic, with a r33 gtr front mount, after market boost controler on 8psi atm, k/n high flow pannel filter,

stock exhaust, and after market excedy clutch

i was raped with my best time and love 2 make it again, so open to any sugestions how to maby even get a better time?

at cadler my mods were exactly the same as what they are now, nothing has changed

cheers.

mt et streets seem to be the go for for pure drag use, but you'd probably need to run them on your stock rims.

[gregor]

also post up your timeslip details. The 60ft time should tell people how well you got off the line which has a big impact on et.

i lost my one from calder lol, i was shatterd, but when i draged then it was on a set of 205 semi slicks on 16inch wheels, they were great, full boost launch at 4.5k with no wheel spin, im thinkin my 265/35/18's will be good enough, they grip like all buggery on the road

Definitely go back to your stock wheels with the 225/50/16's as they will provide more grip on a prep'd track. The thicker sidewall will dampen the launch and allow the heavy car to slingshot from the line where as your 18's are too firm with no sidewall flex and will either create axle tramp or just spin and go nowhere.

A recent example of this theory would have been last weeks Top Gear Australia episode where the supercharged Walkinshaw VE Commodore was quicker on the factory wheels than it was with the Walkinshaw wheels.

If you want to spend some money then get stock R32 GTR (16x8 as opposed to 16x6 for stock gtst rims) rims with a pair of Mickey Thompson ET Street Drag Radials.

As for help with a quicker time, the first thing would be a new full exhaust system to replace the stock, that will give you better midrange power. The second is just heaps and heaps of practice and to keep all your timeslips and collate the data in a spreadsheet.

so what size rims and tyers .and brand ,are ppl using if they want to run a full slick ??

[benm]

Nobody runs a full slick tyre, they are all grooved drag radials (which are a different design to circuit semi or full slick tyres).

sweet as mate thanks for the info very very usefull, the 18' rims live on my car, so ill be driving there on them, but ill definataly have a set of stockies in the back seat, shall try both types and see the difference but i understand your point, with the 205 semi slicks they were amazing on track, i launched basicly flat nacker of the line with no wheel spin, and probably a little clutch slip, iv had a fair bit of experiance, use to drag my old car a bit on track, and this will be the 2nd time with my r33

and yea man not many run full slicks, typicaly a semi slick tire, look like street tires with less groves and the compound of the tire is softer and much more gripy/sticky

Yeh go the 16's. You need sidewall, also drop down the air pressure a bit for the run. Also circuit slicks are not designed for drag and would not be as good as normal road tyres believe it or not.

[benm]

Once you are in 2nd gear semi-slick circuit tyres will still be better than road tyres, provided that you heat them up with a gentle burnout.

Also, no point taking your 16's in the back seat, where are you going to leave them whilst waiting around in line all night? Swap all 4 back to the 16's before you leave home the night before and drive to/from the track in them.

[dyefuker]

its a massive meet for the australian ford forums that iv joined thru a mate that obviousaly has a ford lol, so there all good people, and you get your own pitting/coverd area to put cars parts/wheels/ luggage/subs and amps, n yea anythin not wanted in the car, its quite a good setup there at heathcote,

yea probably a good point thou to go back to all 4 stockies, they are lighter than my rims to!! how didnt i think of that! lol ooops

hey dont know if you read my reply in your topic but read this!

hey man, not sure you even have to do that, i ran 15inch slicks on the back or my r33 gtst and they fit on fine with no problems with the rear brakes, and iv got the 4pistion fronts and 2 piston rears which im prity sure are the biggest stock r33 gtst brakes?

they were 15inch wheels of a au falcon which run the same stud pattern and offset, and they had 205 semi slick tires on them, griped like buggery and made me able to make a 13.5 second quarter mile with my stockish r33

hope this info helps ya

yeah sorry dude ,i missed last night ,when i was looking around ..

cheers for that

[dyefuker]

all good man, i think with the 15's on the back of mine there was a good 5mm clearance of the brake calipers, so u shouldnt have a problerm
