yup, that's the general convention for any car. I used to do it in my teg.

I'm keeping the front higher though, because i don't want any more oversteer than i already get (at least at higher speeds when going around highway ramps).

I dunno, maybe it's just my style of driving and camber settings. I prefer to start turning the steering smoothly, with very small inputs at first, so that the tires have enough time to catch up with the slip angle in front. Then i just turn the wheel even more...that always gives my rear some slippage. And forget about shifting weight to the front before the turn, the rear WILL immediately start to come around.
I guess after all the time messing around with a FWD car, i "evolved" to produce oversteer somehow hehehe jk.

 

Street you can run anything from 32-40 psi
No idea for track...

But you'll need more than 40psi front if you autox... I found 42 front & 35 rear to
be the best... 615s will probably need more psi's...

Probably 44-45 front and 35-37 rear.

(I'm running Advan Neovas, the sidewall is MUCH STIFFER than 615s)


Edit: this is assuming you got stock suspension.. less with coilovers...

 

JT-KGY, why so much less in the rear? That's opposite of the normal recommendation.

 

yeah, the "more pressure up front" thing doesn't make any sense to me either. the softer tire will generate more grip. i understand the sidewall being stiffer will help with handling, but if the tire is too stiff it'll just slide. just like with suspension. if you want the rear to rotate, you stiffen it up more than the front.

 

i could see if you were running an FR car and you needed more grip in the rear. then running higher in the front would make sense. same thing with the way most of the time FR cars run stiffer springs up front.

side note: warrtalon, can you do me a favor and take a look at my other post about buddy club racing spec coilovers. i'd like to hear your opinion on the problem i'm having.

 

i guess a lot of things can come into play when it comes to these types of setups.

autox messes with your mind a lot more than u expect it to.

 

Unless you go to extremes... slightly more pressure increase grip.

Less pressure = Softer tires = More grip

Only applies if you are going straight line... reverse is true when you're cornering
hard because during cornering:

Less pressure = Softer tires = Driving on sidewalls = ZERO grip

Evo has strut suspension up front.. so it's very camber challenged.
Corner hard the front tires will just roll over to the sidewalls and you'll understeer
everywhere. Check your tire sidewalls after each run.

Rear tires doesnt do much during autox times... having lower pressure help it to
"lose grip" and rotate better... and give you more grip when you're accelerating
straight.

This is on stock suspension and autox events only... not sure about track.

 

There's a autox practice this Sat at CA Speedways (for those in socal)...
I'll be there to take a few runs in the morning.
Come as spectator if you like and I'll show u what will happen if you run high vs
low front tire pressures.

 

OT but I find it funny to be termed an "owner" of RT-615's...because tires are like Taco Bell and pints of beer...you don't so much "own" them as much as "rent" them...

 

yup, see, i wasn't the only black sheep here for whom that setup works i wear out my fronts right to the marker; and just slightly beyond if i turn the steering too quickly and go beyond optimal slip angle for a given speed.
thanks for chiming in
