There's 2 different things to address in this statement:

1) In many cases, there's no such thing as hitting the brakes too hard. You need maximum deceleration just as you need max acceleration.

2) I think what you're saying is that you hit the brakes too EARLY, meaning that you then have to accelerate to get into and complete the turn.

Just trying to keep the terminology straight...
I think my point was that a tight autocross is exactly the thing that tests "In many cases." Because in some cases, it's better to brake earlier and softly enough to get the car balanced fron to back to get around the corner instead of threshold breaking at the last moment before turn in like you might do on a larger course.

Ok I think I have a slight Idea of what might be happening. My celica has coilovers and sway bars. It has very little droop/suspension travel. I can pack a tire in the celica in practically every turn and have pictures of the tires being 1ft off the ground pulling into a gas station lol. The S has quite a bit more suspension travel and thats what is making me think I'm going into a turn too hot. Also doing 35 around a corner in the S feels like 75 when comparing it to the celica. First investment...tires that arent dryrotted...second suspension. If I can get rid of some of that travel it may help me get more of a feel for things. Either that or just get used to the suspension travel... but I still need better street tires. ..thoughts?
I have many pictures of my stock Preludes with huge distance between the inside rear wheel and the ground. Well setup modified suspensions will still lift but not nearly as much in the same corner, even with higher Gs. Going over bumps and dips in the pavement can obviously cause increased distances, however, on any suspension.

The suspension does have noticeable roll, especially compared to a modded car, but you may be limited in what you do depending on whether you care about what class you run in. SCCA AS will limit you to a front swaybar and shocks. The big-ass swaybars do decrease the roll but not as much as a set of properly matched springs. That said, the S rolls a whole lot less than most every other street car out there, save for the high-end sports cars...

I'm using Bridgestone RE-01Rs this year since I'm running a local road tire class. Since these only come in 205 and 225 16" sizes, the addition of a swaybar is needed (I have the Comptech on full stiff). Works pretty well, even considering my sometimes sloppy driving.

After you get your tires (yokahama, falkens, hankooks?) Have someone ride
with you and maybe even let them drive your car during fun runs.

I'm still new to auto xing and have only driven the S during an auto x school.
The car was two weeks old and my thoughts on the RE050's was they seemed
unpredictable and would let go at odd times. So I guess what I'm trying to say
is tires make a huge difference in what you feel you can do and get away with.

As far as braking goes you really want to just mash on the brakes and it is
better to brake five feet early versus one foot too late.

Hope this helps

Mac

yeah I run BF Goodrich KDW's on my celica and they are very predictalbe unlike the S2k. combining that with the what feels like massive suspension roll in the S is making me think Im hauling ass around a corner when I'm really at 25mph hah. As far as my class goes we are going to open up a street tire class for cars like the S and you can have mods so thats what I'll be doing next season. If that flops I guess I'll have to break down and buy race tires and go to BSP. I have already started modding but I have to save up and get some tires soon. tx everyone for your help

Sl2ock, you're really handicapping yourself by convincing yourself that the problem is your tires. It isn't. The S2000 is a very different car from your celica and you shouldn't be embarrased that it takes some time to learn. Quit making excuses and just go focus on learning the car.

True but I still feel its partially the tires... they are dry rotted. 52k miles in 4 years I guess. I have been practicing in secret location hehe.

Also you are going from a front driver to a rear driver. Completely different skills set/reaction patterns.

All other things being equal FWD is slower entering a turn but faster exiting so it confuses me to hear you say the S is a lot slower entering a turn, unless it is just the stock vs. coilover suspension differential.

Try driving at the track and following a front driver.

They really screw your line up entering the turn because they are so slow there but since they can put the power down earlier they pull you coming out. That makes it doubly hard to pass them before the next braking zone.

Pretty much, you have to do all your braking before the turn, turn in then as soon as possible gas it out.
