    lifting front inside wheel on turns.

    Hi Cunts.
    Car is a s13 silvia.
    Lightly modified but very competitive in its current chosen format, Hillclimbs.

    I ran at legends of the lakes last weekend and the car went pretty well.
    Felt good. A little bit of oversteer on corner exit under power but it is a turbo car so expected.

    But after looking at photos after the event it cocks the inside front, not massively but enought that its off the ground in a couple of corners.
    Its setup as i would any of my turbo rwd circuit cars, but on the track they always seemed to corner pretty flat.

    Is this having a huge effect on times if its cocking a wheel?
    I know that four on the deck will corner faster than three in a circuit application but is it as critical on a bumpy hillclimb surface?

    Will i die?

    Cheers

    I reckon it's as much the form of that uphill corner and a bit of powerdown squat. Do you reckon the spring is getting to full droop or is the swaybar holding it up a bit?

    The tyre in the air isn't slowing you down, indeed you are likely getting great weight transfer for traction & punch out of the corner......

    Having seen what else you've survived, this ain't gonna kill you.

          Nothing wrong with inside front off the ground. Indeed, pretty much any old escort lives with the front off the ground. As above, softer rear spings/bar/roll stiffness is good to get power down out of slower corners, which is typical of hillclimbs in comparison to circuit racing corner speeds. Power down is king in a powerful rear drive car - you want to play to your strengths and that is to get the thing punching hard out of a tight corner with no more than a roll of the wrists into oversteer after the apex. It's all a compromise as ever...

            Yeah sounds right for hillclimb as long as tge front isn't washing out on the way into corners.

              Factory front. no rear.


              I guess its going to be a compromise.
              Hillclimbs are never going to be perfect flat nor always bumpy.
              It has quite a bit of pace and is easy to drive so perhaps ill just leave it for a bit, maybe play with bump and rebound a bit and keep on having fun.

                  My car does the same (VL) after i changed the valving in the rear shocks to allow more squat, combined with not a lot of droop on the front it picks the wheel up on power down out of slow corners. Works well, with a solid improvement in lap times.

                    Back in the day, RX3's in particular seemed to drive everywhere on three wheels, and were still quick. It's not ideal, but it's more important that the car feels balanced on that track.

                    You could dial it out by reducing front roll stiffness and increasing rear roll stiffness, and find the car goes slower because it oversteers more.

                    Just check there's enough droop from static ride height too.

                      Gibson Motorsport liked to have the rear of their Commodores pretty soft.

                        My old 911 did this at every corner. Stock suspension with front sway bar and semi slicks.
                        Bigger torsion bars all round and better shocks made it handle properly.
                        Soft setup is slow these days with good tyre technology.

                          This flies against all that I've learnt and all I believe to be true.

                          My view of motorsport is that everything you do with a car comes down to it's attachment to the pavement. You can have all the power in the world, but you've still got to get it to the ground. How you use your tyres is how you beat your opposition. I still believe that the softest possible springing is going to work your tyres best.

                            Itís all relative. Iím comparing to 40 years ago. Spring rates have tripled
