Beth - What are your thoughts on the king-pin setup?

Is it worth it? Which one do you prefer?

I ran the kingpin at the act titles in narrow on a verry large and flowing track and finished 4th.
It certainly has the advantage that you can run harder front sprint springs with the high down force front wing the car felt very good to drive. It has a little less steering then the standard front with medium springs. Felt much better with hard springs.

I tried it on our lower grip technical track but was a few 10th slower it just didnt have the same turn in.
Trying the kingpin in wide with f103 tyres for comparison next.

YRF Update.
Last nights test running the car with wide kingpin front end on a medium grip fast but technical track was an improvement, i set my quickest qualifying time by about 5 seconds at this track i usually struggle at. A few things to try next week but a big improvement non the less.
The downside, the Tamiya and Zen F103 front rims do not fit, the kingpin is too long, only the yokomo foam rims fit which are a slightly larger diameter. Pit F103 tyres are still able to be mounted to the yokomo foam front rims.

High downforce front wing and medium springs was the way to go.

Beth.

Has anyone had trouble with the hub not clamping properly on the axle? I had to use a cap screw with a 2.5mm head in order to get enough purchase on it to tighten it properly, had to use a lot of force!

Yes, always make sure the tread of the screw is lubricated with a some grease, it will help get it that little bit tighter.

The other issue is over time the clamp shrinks the axle ever so slightly, but the grease trick usually works for me to oversome this.

And lastly remember to grease often, I had the hub not tighten enough in the first A final, and failed on the first lap, it was just because i was changing the ride height all day and doing up and undoing the hub, once i regreased it it was fine.

This wing certainly doesn't look right? Is anyone else's leaning forward like this?



Using all stock kit parts too. It actually fouls on the rear of the body when mounted. Have checked the way I attached it and the instructions HEAPS of times.

no just looks bent, the plastic on the wings is very flexable, they are not my favourate wings,

just go fast, the downforce will bend it back

Will have to put a mod in it :P

Might try getting a bit of heat gun action on it.

Do any aftermarket wings fit?

Yep heatgun is probably not a bad idea,

and yes all the tamiya, trg, 3 racing, serpent etc fit fine

you just use 2 top screws, the 3rd is overkill anyway.

Default Wheels?

Is there much difference between wheels? I want to get some Pit Shimizu PS-0573 tires for the front, and need wheels to go with them.

What does the offset on the Exotek offset +3mm do for F1? I thought adding track width takes away traction from that end of the car...so why would I want a wider car?? But then I've also heard a wider car corners faster, so...I'm confused.

As far as I know the Exotek wheels give you standard track width? I could be wrong.
