For the street i actually really like HICAS. It's definitely good for mid-speed cornering. I'm not looking to get a lock bar at this stage. BUT that said any cornering at 100km/h or above can be scary at first (i shit myself) because it actually feels like 3x the amount of roll you'd normally feel. The car is trying to HELP turn-in, but unless you know how the limit of how far it kicks the rear into the turn it feels unstable, which is very scary for a novice driver at high speeds.

My advice is for the streets is get used to HICAS and it's pretty good. Learn its behaviour and limits.

For the track and high speeds corners/drifting it's probably better to lock it. What you want on a track is a car that instills confidence; you need the rear wheels to behave how you expect.

I can't find anything good about HICAS. It was designed for the Wallies, to make their car understeer at all times, so they hit things front on, where the airbags, crumple zone and seat belts can do their job. Wallies don't want no oversteer, ever.

It doesn't reduce body roll, that's physically impossible. HICAS turns the rear wheels, that's it, no anti roll effect there.

It doesn't improve mid speed cornering, "mid speed" means you are not on the limit, so there is nothing to improve, you're still not on the limit.

No race Skyline that I have ever seen has HICAS, EVERYBODY from Japan to Germany, from Group N to Group A removed it.

If I want to turn a corner I use the steering wheel and the throtte, I don't want no computer changing the line that I have chosen. I am not a Wally and I like to be in control.

Cheers

Hi Gary. I like your post, i agree it doesn't reduce bodyroll. I reckon it makes the rear feel like it rolls more, IMO that's the 'squirming' feeling you get.

Well for a wally like me HICAS is great. I don't drive a race car, i drive a street car. I can't reach the limit of grip pretty much ANYWHERE safely (passing the limit means over the cliff, for you it's into the kitty litter) so HICAS doesn't bug me that much.

I've decided when i start doing track days i'll get a lock bar to improve handling and shed some kgs. I'm pretty sure most Skyline owners who track their cars take this route...

      Front LSD Quaife , how streetable ?- QDF3L Owners

      By joshuaho96 · Posted

      Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?

      The FD RX7 is the best looking 90's JDM car

      By Kinkstaah · Posted

      in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.

      I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.

      If they just called it the "Mazda Tiffany", it would have been spot on.

      Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
