Lowering

[baron25]

I read somewhere Nissan's don't generally respond well to excessive lowering, and then it said any more than lowering by an inch has negative effects on suspension. Exactly what happens? i want to lower mine about 2-3in but don't really want to stuff my suspension, or have a dog of a car.

lowering causes

excessive camber

problems with the roll centre

If you're going to lower, make sure you get all the extra adjustable arms/bushes & possibly new bump stops that will be needed to compensate for the changes in geometry and height. If you dont, you wont be able to align it correctly. The further you lower, the more extra kit you'll need. IIRC SydneyKid (the guru) suggests that 340mm (wheel centerline to top of guard) is the lowest you can go and still have a reasonable setup - any lower that that and it will suck. I had my GTR at 330mm then got it raised, mainly for ground clearance tho.

"7. Refer #1, but most guys don’t seem to have problems at 360/350, it’s only when you get down to 340/330 that the height becomes an issue. Remember it’s 100 mm under the lowest point of the car, usually the exhaust where it goes under the rear subframe. The bigger the exhaust, the more likely it will be too low.

8. Nope, replacing bushes in the upper arms with adjustable ones is legal. Hence why the Whiteline camber kits are popular.

For camber kits, this is what is usually needed for each height increment, note that all measurements are centre of wheel to guard;

Standard (new) height is 380 mm front and 370 mm rear

360/350 mm needs only the standard rear camber adjusters

350/340 mm needs 1 front camber kit and 1 rear camber kit

340/330 mm needs I front camber kit and 2 rear camber kits"

Chhers, that's what i was after. Looks like i might scale it back a little then, i had a good look at the car yesterday and i probably only need to lose an inch or so anyway.
