Default HPI Super F1

I realize this is an old chassis and no one is using it.... but someone out there knows the answer to this question...

I've adjusted the shock so that my ground clearance is even from front to back... unfortunately my ride height is 7 mm... I would like 5 mm ... my rear shaft bearing setting is set for lowest right height...

How do I lower the front and rear ? I do have a new set of tires on and I haven't trued them down... Is this the reason ?

Thanks for any input....

if its 7mm at the lowest setting that's maybe the lowest it goes. trueing the tires will knock off that extra 2mm. haven't heard of this kit lol

It's the first kit HPI came out with... But There must be a way of lowering the chassis more besides truing the tires ????

Are you sure that you have the lowest bearing holder that associated makes? I have a Super F1 kit but I don't remember what bearing holders HPI included with them. I could be wrong, but they may not have included a complete set. You might want to try the IRS bearing holders they may lower the car a bit more but probably not an extra 2mm if you indeed have the lowest bearing holder available.

Associated ? Not HPI ? I'm not sure... I bought the car used and assembled... but the bearing holder puts the bearing near the top of the motor mount... I assumed there might be three bearing holders... top , middle and bottom... maybe there is a "more top" holder ??? do you remember your Super F1 sitting kinda high ?

I just found the Manual on-line and the kit only came with two bearing holders... so maybe this is the way it's supposed to be...

Buy a set of IRS #IRS1167 Ride Height Adjusters. They will get you as low as you can go. They offer more adjustment than the Associated parts, which I think HPI put in the kit as OEM parts.

The only way I can remember to adjust the front ride height is to change the spacers on the king pin.

That's pretty much what I remember, I think there are plastic spacers that fit on the kingpin.

You have 2 options:
Change the spacers around, as the other guys said. If that is not enough, you can get longer kingpins from rc4less.com or other oval pan car sites. Then you can add more spacers or washers to drop the front end.

You can also run the spring on the kingpin itself and lock the lower arm down by taking the spring and the A009 joint pin out of the arm. Put a screw and nut in the hole to lock the arm. You can also put spacers inbetween the arm and the mount to raise the lower arm, which will bring the car down.

Ouch! If you can't find the arms, Tamiya F103 arms will fit but you may have to switch to f103 wheels (unless someone knows of a way to fit the Super F1 uprights on the F103 suspension arms). At least you'll still be able to run the car.

Ream out the Tamiya parts to take a 1/8 hinge pin, and run the HPI steering knuckle.
