Maybe so Wade but mine is an N/A 6 and i dont always venture out if raining ( i used to have a spool remember) agree /disagree dont people have better things to do then argue on a forum ?
Obviously not , and sorry Tony i cannot provide D.O.T proof either because someone needed them more than i did..
Maybe like Wade says they will end up around a tree and justice will be served!

You guys tried them and say NO!

I drove a Torana with a trans brake and it didnt spin the wheels with a 1.6 60ft on its way to a 10.4 et
Thats what made my mind up to buy those tyres for my lowly falcon before purchasing the slicks...

I say GO for it...but use your common sense

This is getting quite off topic in a way.. the OP wants advice on how to get a quicker e.t., and using these tyres is one way of doing that... but, if we're going to discuss their legality (or safety, which is subjective anyway) then I think we should start another thread; it is an interesting topic.

Same here Wade, started raining once on the way home from WSID, ended up facing the median strip on King Georges road with a touch of the throttle in 4th.

If I go to the trouble of changing tyres I just run slicks, other than that the RA1's do me, I have done a 1.75 60" on them and 1.71 best on ET radials, not much in them for me, they might suit others setups better.

Just giving my experience with tyres, helping the OP make a more informed decision I hope.

Yeh Know of a few guys that have used RA1's, gave them a good rap too.

I would only be looking at tyres as your car is obviously good for 13's - you just got to get some grip
It doesn't matter what brand they are, they're 20's!!!

Dropping the pressures of a 20' tyre aint gonna achieve anything coz its got a 35 profile (virtually solid sidewall) as opposed to a 60 series tyre.

The bigger the burnout on a street tyre (drag radials excluded) the slipperier they will get.

It just sounds like all you need is a bit more time practicing your launch.

when i ran my XR8 at heathcote at the last meet, i ran a 13.7 with 40psi pumped street tyres, only mods are cat back exhaust with bpr airbox, other then that proper street trim! i found launching @ 1000rpm on street tyres was ideal, just a tiny screech and away she went, when i launched at 1750rpm and 1500rpm, it was just wheel spinning like a mofo! Also forgot to mention its a ZF6 spd auto

wow! Lots of replies and some interesting discussion. I reckon the MT as street may not be good as they wont heat enough with road driving if they can handle strip work.

I'm going tomorrow and will do a few runs. First with better launches and then will try the smaller wheels. Running a 3.23 diff and 20's must make my car closer to a 2.85 final drive ratio. I know I get to 110 ish in second where the stock ones peak out at 97 kms/hr (which is why XR8's had a slower 0-100 needing to be shifted to 3rd or so I once read).

Weather looks like it might hold up for tomorrow. Lets see what we can get.

thank you all for your inputs. I'll let you know how I get on.

how did you go last night kypez?

i did my PB on Sunday at Track championship, a 13.704 @ 104.75mph with a 60" time of 2.184. (pity i dialled in a 13.85 in 2nd elimination but that's racing)

my mph is a bit lower than i hoped (have done a 107.9 mph before) and i still have to work on lowering my 60" but im running street tyres at 24.5 psi so it's an improvement.

need to buy some ET streets. anyone have a pair of 275/40 r 17's they want to sell???

Went out to Calder tonight for the first time in about 3 years, ran 14.1 @ 107.3MPH (Previous PB with other mods of 14.0 @ 98-99Mph from memory)

Happy with the MPH considering i don't have a tune yet but the Std clutch put paid to any chance of cracking a 13.xx which was frustrating.

That was running Std Street tyres at 40Psi.

Did you go with the Boosted Boys? MPH is impressive for not having a Tune.

Growler intakes cost more ! ANd i know which one would produce a much better time
stick it to 'em mate, 100% agree when it comes to modding the engine they will spend the $'s but when it comes to tyres people's asses clench tighter than a ducks and it's one of the biggest aspects to do with 1/4 mile times.
