for the most part I agree with you, but sometimes it helps to break it free around a tight corner, as long as you can control the spin, which is easier said than donewuts the purpose of swinging out the back end? im always faster when my rear trails the front, kicking it out seemed to make me spin. i guess its how people prefer things?
truth. RA1's are spec tires in a lot of NASA and SCCA series:up:^^^it was the spec tire last season i think...most the porsches guys i talked to don't like the 888's compared to the RA1 and are more then excited to go back to them(RA1's).
they are their grippiest right before they are chorded. So that means when you buy them new, they get better and better and better:up:
thats what I've heard. and I've heard because of this, the tire life is pretty long.
I'm thinking about some 949Racing 6UL 15x8 wheels with some RA1s for the DC2... that would be a good time.
has anyone else confirmed this? I mainly road race the car, and heating tires up is definitely not a problem. maybe going 15x8 with RA1s could be too much...
but then again, the RA1 seems to be the standard tire for NASAs Honda Challenge, and of course all those cars are quite light.
ive seen alot of the spec porsches run r888's and other cars run ra1's I guess it depends on the setup of the course?

Are you guys talking about the:see thats what I had heard from a few people. I friend of mine has run both tires on his cars and definitely prefers the RA1s.
are 15x8s wrapped in RA1s too much grip for the back wheels? I mean I can always stiffen up the dampening in the rear.
It's really to set it up to make the back end swing out with my current 205/50/15 Azenis.
FAIL.. on my part!!wut were u running? giving info on tires but not telling people what they were is pointless.
The BFG R1s will be substantially faster per lap than either of the Toyo semi slicks.Are you guys talking about the:
toyo proxes RA1 100 temp semy slick
BFGOORICH G-FORCE R1 40 temp full slick
FWD cars will be the fastest when the rear of the vehicle starts to rotate before the front at corner entry. Physics allows our cars to "pull" themselves straight with the front wheels.wuts the purpose of swinging out the back end? im always faster when my rear trails the front, kicking it out seemed to make me spin. i guess its how people prefer things?
Good input on both post.FWD cars will be the fastest when the rear of the vehicle starts to rotate before the front at corner entry. Physics allows our cars to "pull" themselves straight with the front wheels.
Coupled with the fact that the earlier you are pointed in the right direction for corner exit, the earlier you can get on the throttle... and the faster you will be out of the corner.
This type of setup will be the fastest IF you can control it and keep the rear of the car behind you. If you are hesitant and inconsistent with your throttle application, odds are you will lose it. This setup works for the guys who drive their car 110% at all times, who know how to place their car exactly where they want on the track, who commit to the throttle 100% and would never think of lifting mid corner, etc...
For the other 90% of weekend warrior type drivers/track guys, they are generally faster with a bit of understeer as it makes the car easy to drive... not necessarily easy to drive fast, but easy to drive relatively quickly and confidently.
those nitto nt01's look nice and sounds really good too. that price is attractive. and it says you can mount them on a 7" wide wheel... could be a cheap option for meNitto nt01 can be had for $115 225/45/15
949racing tells me they faster than toyo R888 as soon as I get a tracking # from wheels I'm gonna order the nt01 to try them.
Try to stay away from a 50 or 55 profile I learn it the hard way. The lower the profile the better response you will get, the better the car will handle.
On something widers than 205 7.5, 8 or 9 wheel will work in your favor since it make the tires have a wider patch contact with the road. But 7" will do for a 225 tire.
thanks for the info, you know your stuff. So, I am I better off with a 225/50/15 or a 225/45/15 then? Given that the factory tire is a 195/55/15, I was thinking of going with the 50 vs. 45, but I know there are advantages to the 45. Plus the NT01s only come in 225/45/15s. I'm still up in the air between the RA1 and the NT01.A 225/50/15 is pretty large for a little Civic hatch. An Integra could get away with it a bit easier, IMO.
You need to take gearing changes into consideration as well, if the tire is a taller OD than what you have been running previously. 225/15/15 is almost a full inch taller than a 225/45/15.
Running a 225 tire on a wider wheel, such as a 8" or 9", changes the shape of the contact patch slightly. It doesn't mean there is any more rubber on the road, just that the contact patch that is on the road is wider and shorter. This has its benefits... specifically, that each discrete "patch" has less work to do per each rotation of the tire. The shorter the contact patch gets, the more uniform the loading is that is applied to the area of the patch. This should result in an increase in lateral grip.
Theoretically, a shorter/wider contact patch should also be less prone to deformation... and should have less rolling resistance.
That all being said, a 225/50/15 or 225/45/15 will work fine on a 15x7" wheel. Will it be the absolute fastest? No, perhaps not. But it will be a quick/cheap solution and one that plenty of racers use.
