My motorcyclists remark above was meant as a joke which some(one) of you seem to have missed.
Fitting bucket seats, & a harness, to a road car is just plain unnecessary, IMO. You may as well wear fireproof overalls & a full face crash helmet as well.
It's well known, & proven, that to go fast it's best to try slowly 1st & build up to speed with knowledge of the road or track. Follow someone who knows their way around & learn from them. Being smooth is the fastest way & then you won't keep falling out of your seat.
Or you can go hard on the throttle, brakes & steering......making lots of noise & movements......thinking how fast you are but really you're just driving erratically not efficiently quickly.
Read the other couple of posts above, both from people who sometimes drive on the track...you don't seem to be telling them they're wrong?????
It seems to me Clive that the only person to be talking about driving erratically/hard on the brakes/throttle etc is you?, "Slow in, Fast out, Never put the throttle down unless your sure you can keep it down", thats the way
Actually I find that one of the bigger benefits from seating with adequate lateral support is in long sweeping bends, as the lateral force builds the seat provides support and keeps the driver firmly in position, therefore any steering inputs can be accurately made and "feel" through the steering wheel is not lost due to the driver having to use the steering wheel as support.
It's pretty obvious stuff really, all modern mid range and performance cars come with seating that has excellent lateral support, there's a reason for that.
Your comment re overalls/helmet is of course irrelevant, we are talking about the benefits of supportive seating remember
I havent read every post in this thread but I do very frequently drive on the track, often enough to know that anyone that disputes the benefit of proper lateral support is wrong, so yes if someone else has said that lateral support isn't a benefit they are definitely wrong.
Anyway I will leave it there, I find pondering the bl**ding obvious a bit boring!
