I have an f355c, which is not the same car as yours but maybe you'll enjoy some of my experiences: 1) I don't know abou the clutch feel in your car, but my clutch feel always seems the same to me so long as I am accelerating. if I am driving constant speed (foot on gas but not accelerating), then i find that putting the clutch in is a bit sticky at first and then goes down easy. it also does not feel smooth at all, so now i always give a slight bump to the throttle before i bump the clutch in and that makes it much more smooth. I notice it more at high rpm than low rpm. 2) I sometimes skip gears and sometimes I don't, depending on what the track is like. Usually when it's a turn where I ease off the brake more slowly and gradually, then I skip gears. If I am going to let off more quickly, i don't skip. Consider:  Here, I skip gears mostly at 3a (note this is also down a big hill). I sometimes skip gears at turn two, depending on how early i started braking in the first place. I have spun out there before by not giving a good enough blip and going to 2nd (should have done third, because that is a 65-70mph turn). Lastly, the section between 4 and 5a, I skip gears always because of the bumpiness in the track and there is a nice hill you hit the bottom of before going up. So I hit the brakes as hard as possible for just a split second and then ease up gradually as I come into the turn. This is a great place to skip gears because the car is not breaking at threshold and a slight shift imbalance isn't going to spin you off the track (down a hill with a traintack at the bottom of it). Lastly, turn 7/8 is usually a gear skipper sicne you can be threshold braking through the whole braking zone. 3) I would expect you should have *less* pitch with sport on and asr off. I don't think the tires are slipping - I think it's a tire pressure issue. make sure you warm them up then check the pressure and adjust appropriately for the track temp and your tires. | ||

Thanks for all the thoughts. May try 5-2 shifts the next time out. Will have the service folks test drive the clutch and see what they think. | ||

1) sorry cant help 2) I would go from 5th to 2nd. race cars from long ago had bad brakes so they used the engine to slow the car. brakes today are great especially on the 360. engine braking (breaking) is very hard on the engine. use the brakes, pick your gear and go. 3)dont know. may have a better idea after this weekend, I will let you know. | ||

I prefer to brake hard then pick the gear I need, like 5th to 2nd. You would have to give a bit more detail about the bucking. Do you have to adjust with the wheel? If so, you might be slightly oversteering. I have an M3 and a 348 so I see quite a difference between an inherently understeering car (M3) and an inherently oversteering car (348.) Be careful. Oversteering is much harder to manage than understeering, but much more fun! | ||

Tim, Well, I guess it could be either, depending on who you let show you the line at the track. -Hubert | ||

Hugh, engine breaking or engine braking? I think engine breaking wants to be kept to a minimum. Yeah, i know and im sorry in advance. | ||

Scott, I can't comment on all your questions, but about the following I can: --2) When coming off of a long straight into a tight turn (say from 5th gear to 2nd gear), and given heal and toe downshifting, is it necessary and/or good to go 5-4-3-2, or can you brake hard and then just go 5-2 (I have a 6 speed, not an F1)?-- I always row through the gears as I'm coming off a long straight, as in 5-4-3-2. I feel that it's a bit easier on the gearbox, allows greater engine braking, and doesn't upset the car nearly as much as breaking hard and going directly from 5-2. Also, all the instructors that I've ridden with have done the same. Hope that helps. -Hubert | ||

Just took my 360 to the track (the smile is still on my face) and I have some questions for the experienced track junkies on the site. 1) When shifting above 7500 rpm, the clutch "feel" is very different--is this normal, and is it a function of RPM? 2) When coming off of a long straight into a tight turn (say from 5th gear to 2nd gear), and given heal and toe downshifting, is it necessary and/or good to go 5-4-3-2, or can you brake hard and then just go 5-2 (I have a 6 speed, not an F1)? 3) In tight turns, with "Sport" on and "ASR" off the car seemed to pitch (?buck) a bit--is this the street tires sliding/gripping/sliding/gripping? It wasn't classic understeer (as I'm used to in my M3). I understand the information above isn't very detailed--if someone wants more detailed info please ask. Thanks! |
