rob83ke70 Posted July 6, 2009 Report Posted July 6, 2009 I know how axle tramp is caused and all that stuff, and I've read a bit about it, I've just got a few questions. Has anybody on here ever bound the front of the rear leaves together as suggested in the faq (also mentioned on brindabella motorsport club forum) so as to make the front of the spring pack like a control arm, and the rear still acting as a spring? is it worth adding half a leaf to the front of the spring pack on top? if so, should it be a thick leaf or a thin one? I haven't got any experience with these things (was born 30 years too late) and I'm trying to walk the fine line between too stiff springs causing less traction and axle tramp, the current problem. do nolethane bushes make much of a difference? some people I've spoken to don't seem to think that it would. would nolethane swaybar bushes make a difference to axle tramp?

towe001 Posted July 6, 2009 Report Posted July 6, 2009 Make sure your not using lowering blocks, it'll aggravate the tramping. Caltrack (?spelling) bars are good but they do affect the suspension Tramp bars (slap bars, traction bars) i think are better but they can also have side affects especially if (or when) the rubber stoppers wear out. But they don't effect the general suspension movement as much. Adding half-a-leaf as you've said would be the go. It still does effect the general suspension movement. But you can fairly easily adjust the the action of the half leaf - thinner, thicker, longer, shorter. Nolethane bushes wouldn't really do anything cause whats happening is that the leaves are winding up the wheels loose traction and the spring unwinds, gains traction spring winds up, looses traction. The bushes more help with side to side and rolling movement. If your not to worried about a bit of fab work - a Reese bar is good Quote
Felix Posted July 6, 2009 Report Posted July 6, 2009 Does the car have heavy duty shocks in the rear? Stiffer shocks will help. Quote
rob83ke70 Posted July 6, 2009 Author Report Posted July 6, 2009 car isn't lowered, not keen on lowering blocks anyway. trying to keep some ground clearance :wink: monroe gt gas shocks in rear, very very stiff. caltrack bars are too expensive. we have universal slapper bars that I haven't put on because I'm a little stressed about ground clearance. was trying to think of a more efficient way of doing the job.

coln72 Posted July 6, 2009 Report Posted July 6, 2009 This may be a bit freaky but soften the rear up. Had a KE35 that tramped like a bitch which had Monroe GT Gas shocks and a KE20 that wouldn't tramp at all which had softened rear leaves and standard shocks. Can't say that this was the cure as there were a few too many other differences. Quote
Felix Posted July 6, 2009 Report Posted July 6, 2009 Fords "Quadra-Shock" system as used on some of their 80's mustangs looks interesting. Quote

Can't say that this was the cure as there were a few too many other differences. I'm not sure of the length of the leaves between models, but I wonder if there could be any difference there? My old ke30 used to have tramping issues with Monroe GT Gas shocks on the back. My ke15 (with about 2x the power) hasn't really had any problems running fairly sticky yoky tyres, but it has very firm Tokiko Oil shock's on the back. I did snap the center bolt of the leaves on the drivers side at one stage and noticed a bit of tramp afterwards until I replaced the leaves . Quote
coln72 Posted July 7, 2009 Report Posted July 7, 2009 We have solved the problem - don't run Monroe GT shocks :wink: Quote
towe001 Posted July 7, 2009 Report Posted July 7, 2009 Fords "Quadra-Shock" system as used on some of their 80's mustangs looks interesting. Looks like a take on the Reese bar but with leanings to a 4-link suspension. :wink: yeah does look interesting. Just would have to figure out on the right type of shock absorbers and placements of the brackets Quote
Boost+k Posted July 9, 2009 Report Posted July 9, 2009 i used to get alot of tramp in my ke70 wagon, i added a half leaf upside down on the top and removed the overload leaf and it transfored the car, made it nice and smooth to drive with no tramp, you also have to make bracket thingies to hold pack togeather i now have put the overload leaf back in because i use the car for drifting so wanted it stiff again (still have half leaf) also turned one of those bolts that hold the pack togeather into a S shape lol, just replaced it with 12.9 grade cap bolts and been sweet since Quote
tojo2 Posted July 9, 2009 Report Posted July 9, 2009 Heres a how-to on a diy caltrack. Kind of makes sense when you look at it http://www.hotrodsandhemis.com/Traction.html Quote
rob83ke70 Posted July 12, 2009 Author Report Posted July 12, 2009 we were quoted around $500 to reset the leaves, add a rebound leaf to each pack, and install nolethane bushes, including all labour.... was thinking that might be the best solution. Robert. Quote
Falken_KE30 Posted July 12, 2009 Report Posted July 12, 2009 I got an added leaf, and them reset 2" and i don't get axle tramp, then again i don't clutch it off the line when i drive so i wouldnt know. But general driving, and around windy roads its amazing, so much firmer and more direct Quote
