Hicas was removed for the race cars as racing drivers didn't like it I read.

Doesn't hicas improve turn-in by steering the rear wheels in the opposite way then stabilise the car by steering the rear wheels in the same direction as the front wheels through the corner hence exacerbating understeer, which a lot of race drivers hate as it slows them down.

Race cars will run loads of neg camber to assist high speed turn in, so hicas would prob only help with low speed turn in.

I am a little nervous going to a race track with hicas as it seems it can play up (particularly on GTR32 which have a less refined, slower reponding system).

Come to Castel Combe on the 21st March and I'll show just how "slow" I turn in LOL

As I said earlier in the thread, you have to learn to drive the car totally differently from what you were taught, once over that fear and trust in the fantastic clever system (which even Porsche have now copied) that Nissan developed to make the car corner FASTER you will not want to remove it or go backwards in the dark ages of having to errrr drift (slowly) round a corner !

hi-cas dose not exacerbating under steer , it gets rid of it !!!!!!!!!!!!! , and , Don`t get offended , but , but My mate told me/I read somewhere dose not cut it , show me the article that Japanese Race drivers took Hi-cas of there R32 , if they did take it off ( as you state - it was to suit there driving style) , and not for speed !

Gibson motorsport cars also deleted Hicas I believe.

Maybe the racing drivers couldn't relearn how to drive properly, but, you have to admit they are pro race drivers with big bucks teams behind them. If hicas was faster (for a race car) I'm sure they would have used it.

For the road maybe it's better.

Steve, any 600bhp GTR will be fast - would it be faster without hicas and would you prefer it is the question? Surely you would need to test with & without, timing yourself.

It may be that different driving styles would make a difference too.

I will drive my car with & without, then make my mind up.

Cheers,

According the R34 Falken driver, he said "We do not have HICAS on our race car as, with it on the car is easier to drive but not faster. Thats why we don't have it"

For race cars is something diffrent, but the car is designed to be used with HICAS, but i do understand the people that remove it due to the fact it is faulty and worn, so it would be cheaper to just remove it than overhaul it.

Rasored,

Yep, all good at the mo - Abbey replaced all parts that were worn, so should be operating well at the mo!!

Unfortunately due to engine letting go I have not been able to drive the car in anger for 18months!!

Hope to be back on the road soon and hopefully a trackday later in the year.

Cheers,

I heard if you remove it on the 33 it makes the power steering heavy at slow speeds?

Ha indeed Though I have no particular intention of removing my HICAS, even if I did and the steering did get heavier I wouldn't really care - the steering is light as a feather on my 33 and I can almost turn the wheel with my nasal hair.

Cheers,
Kingsley.
