pararbolic springs anyone?

[84pickup]

hey guys,

i was wondering if anyone has used paraboic springs on their pickups over here. http://www.parabolicsuspension.com/toyota/hilux.htm this is a link to the maker of said spings. if you go back a page it has a more general desciption i think. also if you have suggestions for good DD tires but still good for 4X4ing. i was thinking about getting some BFG M/Ts but i'm not sure how noisy they are or how much fuel economy is affected.

I have 33x10.5 BFG MT's and stock gears and about 1.5 inch lift, and can get 20 mpg on the highway. Yes, that's corrected for the differing mileage on the odometer. They are not too noisy and I like them a lot.

Interco LTB-01, only letdowns have been getting cuts on wet Shale Rocks and severe tearing of the tread on dry hard dirt like when in Ruts. Brilliant Tyres on Bitumen, though.

well i'm getting about 20 MPG right now with no lift (i think) and 235/75/15Rs with stock gearing but anyways, do you have an equation for correcting the odometer or do you just know.

It's a ratio, not the ol' "My speedo is 5 mph slower than I'm going...." My actual speed and distance traveled is 1.16ish times what my speedo/odometer says. That's because stock tires (225/75/R15) is about a 28.3 inch tire... times 1.16 is 33ish inch tires.

Those springs look really stiff
