m1ghtymaxXx Posted December 21, 2012 Share Posted December 21, 2012 My apologies if this has been covered somewhere, but in my searches I could not find a clear answer. I've read numerous times that 240Z racks are lighter (aluminum) and quicker ratio than 280Z units. I was thinking of getting short steering arms, but realized shedding a couple pounds and quickening the ratio with a 240Z might prove more beneficial. In searching for rack interchangeable I found this ancient thread: http://forums.hybridz.org/index.php/topic/37106-240z-steering-rack-interchangeable-with-280z-steering-rack/ which states that racks are interchangeable between all S30 years, but the 78 has the quickest ratio (I have a 77). Can anyone confirm whether the 240Z rack is in fact quicker, lighter, and fully interchangeable, perhaps backed up with some numbers (weights and specific ratios). While I'm at, I welcome you to weigh in on my theory; I only got a chance to autocross once with my S30 before winter, but I found the manual steering to only be a significant detriment to performance when turning hand over hand, so I figure by having closer ratio steering it will increase steering effort, but I will be able to perform tighter radius turns while keeping both hands planted on the wheel.

Savage42 Posted December 23, 2012 Share Posted December 23, 2012 Well, you got part of it right. The 240 rack does indeed have a quicker ratio, that much is a given. The only difference in the rack itself (between the 2) is that the 240 rack has aluminum spacer/mounts compared the 280 rack, which uses larger bushings since it doesn't have the aluminum spacer/mount on it. The rest of the rack is the same, so there is not weight savings to be had. You just have to make sure you the the correct rack bushings to match whichever rack you use, but it is a direct bolt-in swap for quicker steering. That is all. Hope that helps. If you want quicker & lighter steering, look at the electric power steering setup. Quote Link to comment Share on other sites More sharing options...

I have seen many attempts at custom ones but have yet to see it successfully done. Thnaks, Rimal Quote Link to comment Share on other sites More sharing options...
