We have around 100-110mm [4-41/2 "] up travel to the bump stop in the front, and 120-130 5-51/2"] ish mm in the rear, giving me my favorite option of 1/3 up and 2/3 down travel, so, with the shocks running within one inch of bottoming with our 40mm [1.5"] bump spacers, with a 12" stroke front shock, valved to suit a well equipped cruiser, and the shock length goes close to bottoming the steering tie rods, and we will set the adj panhard rod angled, so it compresses the bush easier on up travel, and will allow full droop without binding, now, as per this pic,

We have also machined new alloy housings for the internal bump stop cushion to move it down 40mm also, and with this spacing, on the 17 x 8 rims, the tyres just touch on full compression, on part lock, and moving the front axle forward with these

will prevent any tyre rubbing, with only a slight modification to the rear of front fender, around the mudflap, with a hammer, to make some room, while keeping it looking factory.

In the rear, we are using a 12.5" stroke shock, that is also close to fully compressed when car is on bump stops, so I get maximum droop from the shock length Im using, when the bump spacers are installed, to help fit the tyres. The rear tyres are rubbing on the mudflap area at compression in the rear, and some "massaging" and if required, a 1/2" body lift, using all the factory bolts will be added, to help with clearance.

If you look closely at this pic,

you can just see the middle bump cushion extension sticking up over the coil at the bottom, and the alloy spacer under the chassis bump stop. The internal one bolts to the hole on the housing spring seat.

The sway bar extension lengths are critical, so they dont limit up, or down travel with the shocks we are using. The fronts with the new shocks we have had to go to 70mm extended, rather than 40mm to prevent the sway bar hitting the front tailshaft at full droop.


Yesterday, taking the car out for a run, we jumped the vehicle twice, where we have an old train station platfrom we can jump up onto, and after turning off the road at over 65mph into the bumpy gravel section, sliding tail out left, then right, and adding some brake, to stready the car as we hit the up onto the platform, and the car went up, and down, very nicely, and had no tyre rub, and the suspension is working very well, and will improve, once we add some weight in accesories.

We also have a back small gravel road in an industrial area, badly corrugated and big potholes like 4 ft round, and up to 8" deep, with a 45 deg corner on it, where it is worst for bumps, and generaly a good handling lifted 4wd should be able to go around there at up to 85 mph, [and we do regularly] in a nice 4 wheel slide, controlled, but quick, yesterday at 65mph, the car was very composed, no bucking, no understeer, no oversteer, nothing sudden that could catch you out, so once it has some more power, we will continue to push it, but very happy so far.

Dual batteries were fitted today, and wiring, so will post some more pics [inc water tank] in next few days.
