Red Devil mkII - The Journey Continues

[seangti]

Glad it's all starting to get sorted out.
When is the next track outting?

Timeattack at Lakeside on 11th October.

The Kmac tops will make some noises kind of like the spring binding as they don't have bearings in them like the factory stuff.

The car now has a 65/35 (f/r) balance. Ride height looks a little funny with a higher rear to front. Though looks comes second to handling.

Rake, it's called rake. Most race cars have rake except maybe F1 and some cars where the rear can't have a decent ride height due to geometry problems from the manufacturer. Rake aids in aerodynamics to create more down force at the front.

To keep your settings avoid pot holes, gutters and general wheel banging as this will change the geometry setup when travelling to and from events.

The springs should not rattle around. The camber tops will hold the spring in place by either a poly style bushing or a spring top retainer. Make sure that the shocks shaft is done up all the way and that the shock shaft nut does not protrude away from the base of the camber top when the wheel is on the ground. If it does, simply pack it up with washers under the camber tops, this is a normal practice.

Now enjoy and play with those tyre pressures. Ask your tyre supplier about starting pressures....

Thanks again, always welcome input.

I could have better explained the kmac tops. Whereas the factory tops have the strut top bearing to allow the spring to rotate against the mount, the kmacs don't use a bearing or poly bush. It's a metal to metal contact which allows for rotation in a pillow ball joint arrangement, inherit in it's design makes some binding like noise at that point. It's not the spring to mount binding noise. It's not an issue, Ken at Accurate Suspension mentioned it, and yup, a little metal to metal contact noise on turning.

RE Rake - yup, knew there was a better word. Having done some more research yesterday, I'd say having rake on a FWD car will also improve power down out of corner due to weight transfer. Obviously this can be offset by too much camber. It felt a little grippier under throttle yesterday.

RE tyres, I've probably only got another couple of events on the current semi-slicks and will probably than go for the yoko AD08R as a single street and track tyre. It than puts me in the street class for timeattack.

Great update. Glad you found Ken helpful and competitively priced.

Street class is where it's at mate, then I may have some competition

Re: your comment about improving power down out of the corner. Ken also recommended some firmer springs in the rear, he's trying to move me into a 750lb replacement for my current KW.

Great update Sean can't wait to see the lap times tumble!

Not sure about being competition for you mate, your laps time just keep dropping. My current aim is mid 63's at lakeside, with more time in the car I don't see that as over reaching. Last outing I wasn't getting a clean run onto the straight, I didn't have the confidence to commit to that final corner.

You're always welcome to have a steer with the new suspension. You won't recognise the ride height though, it's like a giraffe.

Pic? Haha

[seangti]

Pic? Haha

I'll try get to it on the weekend after giving it a bath.

[seangti]

Spent the afternoon washing cars. My two and the missus. I won't share pics of hers...

Ride height wise, from ground to the highest point of each guard, the fronts is 60cm on both sides, rear is 62cm on drivers side and 62.7-ish on the passenger side. Not sure why the difference, could be intentional, or not. All our tracks are right handers, so whether having the rear left marginally higher aids turn in or grip... I'd be making it up to suggest either way.

The rear is probably near on 2inches higher to how it was when I bought it, so the car formerly known as red devil is now the red giraffe, haha I'm really chuffed with it now. Arghh, come on October 11.

So how did it go out there today Sean.
It was pretty warm out my way so i imagine the seat intercooler and tyres would have got a workout.
