Ground clearance front and rear?

Just wondering what you all have your ground clearance set at, not the lowest part of the car(exhaust, sump, whatever) but the measurment front and rear from the bodywork to the ground? This would be very helpful to me with my custom chassis and suspension.
Thanks

2001 JPS flared body.
Front: fiberglass to road = 7.5 inches.
Front: bottom of nerf bars to road = 5 inches (they scrap occasionally.)
Front: bottom of rubber air dam to road = 4 inches (hey - it's rubber).

Rear: fiberglass to ground = 9.5 inches.
Rear: bottom of nerf bars to ground = 6.5 inches (they scrap occasionally).

In retrospect, I'm really glad I got nerf bars! They are working, though I think not as originally designed as bumpers.

Thanks David, do you have any pics of your car?
I was thinking of making my ride hight 6 inches front and 7.5 inches rear, in your opinion is this too low?

Hard to answer your question, because I just lucked into my solution. It depends on your local driving conditions I would think. The bottom of my nerf bars frequently scrape (nothing serious, but the chrome is sure gone) every time I leave my driveway. Several local streets have serious "rain gutters" at intersections because they were paved too many times without changing the whole grade level. Some speed bumps (not many) cause problems. Because of my nerf bars, I don't really worry about it. But they definitely contact the pavement nearly every ride. Now if all I had down there was a fiberglass valance . . . that would really concern me! Granted, not many owners like nerf bars. Maybe a hidden "skid rail / plate" that hangs just below the fiberglass?

Mick; if you look at original 356's, their stance tends to be lower in the back; they certainly look mean that way.....

Ricardo, the stance does appear to be lower but I think that is because of the rear wheel arch is lower than the front rather than the ride hight being lower, yes I do agree with you that it looks mean but I would like it looking a little meaner, not too much as we have a lot of speed bumps in the UK.
Chassis is coming on well, all ready for sheet steel, I just have to make a hydrolic press after the Easter break to mould the floor into somthing a little more ridgid as it's only 1mm thick.

David I was thinking of some sort of skid plate, I have a large sheet of 2mm stainless steel knocking about. I have clicked on your info but still can not get photo's of you car, am I doing somthing wrong?

Mick, no photos. I'm an analog guy. That's why I own a speedster! My wife is more digital, but she hasn't been sucessful in "training" me how to download and store photos. 8000 pixs of the grandson, and no speedster pix. Can this marriage last another 40 years? Maybe, if I stay out in the garage?

Thanks for you time David, it's a shame that you can't get pics of your car on the forum, it's always good to see what people are up too? Maybe get your wife to take pictures of your car and upload them, you know what they say 'why have a dog and bark yourself':-)
