Default is it me or does our car suck on the twists

Especially at high speeds. The car seems to lose control after a slight turn and 115

Guess it depends on how "slight" a turn you're referring to? I haven't tracked mine (would love to see on a road course), but it handles well on all the highway roads I've pushed it on.

Could you be a little more clear on how you pushed it that you weren't happy with?

I drove the IS-F at Laguna Seca and it feel very composed in high speed turns, but 115mph is not in the "the twists", in a twistys-like canyon road, the car feel fantastic.

May I suggest do not lift the throttle too quickly while you are in the turn, actually you should not lift at all during the turn, you should have lifted before getting in the turn and slowly reapply power as you unfold the steering wheel and track out of the curve.

I feel like there are improvements to be made in the rear bump steer, but in general I am surprised by how well it is out of the box. High HP cars require different driving technique just like the diff between a 600 sport bike and a GP racebike. If you punch the power at the wrong time, you will lose traction, simple as that.

Where were you running this when you had issues?

My previous fun car was an '04 S2000. After getting this car, I tried taking it to the same backroads I used to take for fun with the S2k. The ISF definitely doesn't feel AS nimble on tight roads. The suspension on the ISF also is more punishing. Perhaps the stiff suspension combined with the weight of the car makes it feel that way. I'm not sure.

BTW, anyone else notice or wonder why the wheel/fender gap is larger in the front then the rear?

I noticed too, but remember your ISF is 1000lbs heavier. For a car that heavy the car handles well. The only other car that I like better is the GTR, which is everything that I want in a car, looks aside.

The fender gap in the front is not that nice looking, but everyone seems to be lowering it to make it even. I'll put my money on the fact that it's to help the weight distro get to 50/50 and once you lower it the car will plow even more and be off balance, which is why i haven't lowered mine or plan to.

Unless you lower the whole car F+R at the same proportion I think it will affect handling.

I don't agree. The pre-production cars they showed in Aug 07 were lower than the production cars and they handled fine at the track. My guess is the higher ride height has to do with passing low speed crash tests with less $$ damage to the car.

I couldn't see how .7" would really reduce the costs of low speed impact. the front end will be hooped either way.

I'm not saying you can't lower it, rather the rear and front have to be lowered in the same proportion.

The car has to be front heavy, consequently to offset it they raised the front a bit higher than the rear.

The front gap is always going to be more to make room for steering angle. Its pretty steep on this car. Same with the Gen one IS

Sorry to disagree, but the IS-F I drove at Atlanta Motor Speedway plowed like an agricultural implement if you roll on the throttle through the turn. I had a long chat with the lead driving instructor, and his comment is, neutral throttle all the way until you see your track out line. When I tried to roll into it, the way I do on bikes and in my Supra, it pushed enough to give me a brief tour of the grassy areas. This was on Michelin PS2s, not Bridgestone, so I know I was on the best tires available for the car.

I'll be figuring out how to add negative camber to the car shortly after I decide I want one in my garage.

Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.

Emotional arguments - They're not just for chicks anymore.

What I noticed with my car is either the amount of traction or the lack of torque?
From a stand still, when I floor it the car just bites in and goes, no screeching of the tires just up to speed.
I've tried this with the traction control off and in sport mode, also only in sport mode, and then again with both on. The only difference seems to be the response.
In the twisties I've taken the car on no sign on plowing...gets a little loose in the back, but as mentioned throttle control is the key.

How many F's are now in 50? Dropping gas prices (especially at COSTCO) must really be helping you...
