R34 Gtr Ride Height Help!

[spec-l]

Hi , I'm looking for some help/advice.

I finally got around to putting coilovers in my bnr34 and was wondering what ride height others are running?

I have them at fairly even heights front and rear atm.

Any help would be awesome! Btw I have 19 rims.

Thanks

Rims make no difference, but rolling diameter must be the same within a few percent to be legal and to make sure your speedo is accurate.

IIRC all GTRs are the same with respect to hights (but i'm not 100% sure). So you want lowest of 350mm front 340mm rear (wheel centerline to guard). If you want higher, say if you have clearance problems under the car, then just make sure the front measurement is 10mm higher than the rear.

If you're going to track it, get it corner weighted after you've settled on the height you'll run.

Thanks for the reply. That makes sense but why 10 mm higher in the front?

Are gtr's like that with standard suspension?

[MrStabby]

Not sure. I always assumed so, and assumed it was because the opening in the front guard needs to be larger to allow for the wheel movement when steering.

It's not 10mm higher in any sense except the distance from the wheel centre to the guard lip. The fact that it comes out that way says as much about the shape of the wheel arches front to rear as it does about the suspension.

Sure thanks. Any opinions on camber settings?

I've got -2 on the rear atm but I think it's too much, especially because I have high spring rates and I'm going to put adjustable sway bars in.

You want the least amount of neg camber on the rear that works. So the usual range is about -0.75° to -1.0°. That tends to give the sort of compromise between straightline grip, tyre wear on the inside edge and cornering grip for a street car. A stiffly sprung track car on sticky tyres might want to run a lot more camber.

The same rules apply at the front but you can run a little more camber. Up to -1.5° is the normal range. But again, your mileage may vary, depending on how the car is used, the tyres, etc.

Thanks, I thought so.

I'll play around with it abit to see what works best
