Complete R34 Gt-r Hicas Removal...

[xanavinismo]

Hi all,

I would like to completely remove the HICAS system in my R34 GT-R (instead of just a cancel rod etc etc) because of the weight saving (20kg's?) and the benefits in handling but am curious to know the procedure for R34 GT-R's... I have read the threads which describe the R32/R33's but its not a complete removal... just cancel rods and not on an R34 GT-R...

Im guessing that it would be pretty much the same, (Ie - remove the rear steering arm, fluid resuviour tank/lines & motor in the boot) but I am interested to know of other R34 GT-R owners who have done this before...

Cheers,

bumping this as I'm also very interested in finding out if this has been done before

umm its not the same as a 32 at all as it's not a hydraulic system. there are no lines to the front of the car or solenoid in the engine bay to worry about. the resoviour in the boot is for attessa not hicas.

as for the actual hicas rack - the lock washer option locks the standard rack in place, or you can get a hicas lock bar to replace the standard motor. If you really want to remove it altogether you would need to convert it to an s13 style setup with tie rods instead of a hicas rack....there is some information of how we did this in our racecar in the Builds section

Thanks for your info duncan. So the hicas motor does weigh a fare bit? Also, does that mean I wouldnt have the problem of having the HICAS light coming on because there is no solenoid in the engine bay?

I found these Midori Hicas Cancellers... it looks like it will save a heap load of weight!

Link: http://www.midoriseibi.co.jp/tuning/others...-canceller.html

Also appears that they bolt up to the standard mounts where the Hicas normally goes with no bar in between what so ever. Although more expensive than a 'Cancel Rod' these seem like the closest thing to complete removal of Hicas without much fuss!

However, has anyone ever used these?

I'd prefer a decent lock bar instead of a bit that bolts on on each end as a bar is much more rigid and doubles as a brace. The good ones are hollow aluminium and weigh bugger all.

[big_d]

yeah, but the brace doesnt get rid of the hicas unit itself so no real weight reduction.

just googling 'midori hicas canceller', there seems to be somewhat of a review on the product: http://minkara.carview.co.jp/userid/424045...0193/parts.aspx

not much info, but its got a pic and looks like what you're after.

A lock bar replaces the HICAS rack and motor etc so definately saves weight.

[big_d]

ah yes, i apologise, you're correct.

Cusco also make a similar product to Midori Seibi's hicas cancel rods - Cusco Drag Rod: http://www.nengun.com/cusco/drag-rod
