not sure if this is an r35 only thing, but I found it really interesting....

back in the old days, cars had a seperate chasis built like a ladder. then you bolt the car/cab on top

someone thought up making the chasis part of the body, lighter and just as strong. so they welded 2 chasis rails to the bottom of the floor plan instead of bolting a ladder on, and created the unibody chasis.

nissan obviously were trying to create a flat floor for good aero, so they sat back and looked at what sticks down below the car - and came across the chasis rails.

when you strip the carpet out of an r35 , instead of the normal steel floor and tar you see fitted high density foam. (in fact there's almost no tar in the whole car).

Lift up the foam, and there is the chasis rail running down the middle of the floor, the foam brings it up literally 20cm to make a flat floor.

looking from underneath the difference is really clear - flat sheet metal for nice smooth air flow.

must be a real pain to build and repair since all the cutting and welding will be inside the cabin, but for now it is an interesting idea.

yeah thats what they are after with the rear mounted box, and it makes the rear passengers (poor bastards) sit very high with a knees up position.

but it was the wierd chasis rails that caught my attention

yeah wish I'd got pics now. Russ if you get your hands on one sometime you'll have to post up :ermm:

it does mean once you strip carpet and foam you need to create a checkerplate false floor or something. and the seat sits amazingly high above the chasis floor, plenty of space for a big amp or whatever

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
