I've got a 06 td cruiser, need advise on the best set-up for something a bit harder in the suspension side of things.
I've already done a post previously, but trying to narrow it down before I do the job. I carry a trail bike on the back of my tow hitch (350 exc KTM, 115kg). Do a bit of fast ,dirt track stuff on corrigations, some slower 2nd stick mud, pot hole stuff, and on the beach (not yet, but will soon) .
Any one got some good ideas on shocks and springs, are those poly airs any good ?
Cheers
Glenn

I am on my second IFS LC100 now and this time I have just fitted rear OME springs (carried over from the previous vehicle) only. I then wound up the torsion bars 25mm (you can get up to 35-40mm). After looking at adjustable shocks I decided to leave the standard ones on. The standard shockies are better than they get credit for and I could could not pick a differnce to the OME shocks on my previous LC100.

I had polys on the previous LC100 and they are great for very heavy loads. If your loads are only moderate the OME coils will do the job.

If you want to lift it more than an inch you may need to upgrade to shocks with more travel.

I tow a 3000kg boat so have more weight on my towbar than you will with the KTM. The lighter OME coils handle this well. OME do a heavier (rated 200kg more?) coil too.

Save yourselve some money and start with the coils only. Wind up the torsion bars yourself and get a wheel alignment straight after that. Just make sure your front wheels will still droop 60-70mm when the weight is off the wheels. Measure this from the rim to the guard on each side with the weight on wheels, then weight off wheels.

If you are still not happy then look at new torsion bars and shocks.

Topend.

hey topend
not sure what you mean by the droop.? Is that when you've got the wheels off the ground ? I've heard you can only get an extra 35mm lift on the 100 series from the original torsion bars, is that correct ?

Did you put the strenghting bracket on the IFS A frame.? The guy down at tjm said they have upgraded the 06 model, not sure if he right or not. Any advise?

Glenn,

35-40mm I believe is all you can raise the front. I only went to 25mm this time, 35mm on my old TD100. The droop I mention is the measured difference between when the vehicle is on a flat surface with full weight on the wheels and when the vehicle is jacked so the weight is off the front wheel. The more you raise the front suspension by adjusting the torsion bars, the less this will be.

To prevent the Shocks topping out you need at least 60-70mm droop. The most accurate way to measure is run the tape measure from the bottom (or top) of the rim to the guard. Don't measure from the ground.

Toyota has upgrade the bottom wishbone. There was a recall for older models to inspect the front IFS.
