I went out today and it rained, but I ran the car anyway after a few minutes. The car ran great, but I need to know if I can use better upper rear links and ends, and steering linkages and ends. Anyone have a recommendation? The steering has too much slop and the rear linkages are too delicate. Now, this is coming from someone new, so don't take this into too hard of consideration if you are buying the kit.

A fellow racer down said that ride height should be set at 5mm, mine was set at 8mm. Doesn't this factor into long races since the tread of a tire wears down?

I notice that the rears tires wear down fast, I know this is normal, but should not be the case since I was running 42R/40F. Is there some overdrive built into the belt/pulley system?

Last but not least...droop. Someone said that I had too much uptravel, how are you guys setting this- measurements?
XRAY makes some nice ballcups for the steering rods and Kyosho makes some good ballends for the rear camber linkages. Should be a fairly cheap swap.

Ride height is a local knowledge thing so if he said 5mm and he is fast then believe him. The tires do wear down over a long race so you need to compensate.

There is no overdrive and some tracks are just flat out abrasive. Also your setup and the smoothness of your driving affect rear tire wear, or tire wear in general.

I run 0mm front droop and 3mm rear droop usually on foams on a fairly grippy track.

I do need to reduce the droop in my front. Infact the front tires hardly worn down, while the rear is nearly down to the rims!

Thats fairly typical wear rates. I usually wear my rears twice as fast as the fronts on a really high speed track. Overdrive does not overcome this really.

So I guess just buy new rear tires and leave the fronts?

Yep I do 2:1 normally. I run the fronts at 59-60 to start with and 61-62 for the rears. When the rears go away too far, go some new rears cut to the appropriate size.

I have been racing for a few years with different engines, cars, tracks, setups, tires shores etc and the 2:1 wear rate still seems to be more or less the same now as it was back then.

Like I was saying in another thread if your car is loosing rear traction , just try a softer foam....unless your already at that point.

You can go with the softer rear. Spring or Sway. What kind of spring are you running. I have the proceed red and for the little amount of time on the track my car handling pretty nicely , the front would turn well and the rear never came out.
ok I was running 38 front/ 40 rear jaco nitro shoes.
still running the stock springs
3mm front / 4mm rear
graphite towers front & rear
stock rear sway bar
front sway bar set 90* vertical
4 gear diff rear w/lt grease

only changes I did was to put in the 4gear rear diff and change the front sway bar to 90* vertical instead of horizontal. I never had a problem with the rear before now.
the track surface is high bite never had a problem running 40 in the rear.
body was a hpi ford mondeo.

Setup seems ok. Ford mondeo is a big NO NO generally.

hows the hpi NSX work on the track?
If thats not so good I can always fall back to my Skyline body it kills the high speed steering a bit but is very stable at high speed and I can push it thru the turns at slower speeds.

My new body:



This is not my ACTUAL body but what it looks like.

You will find if you are racing people with Alfa, Mazda6, Stratus 2.1 or 3.1 or any of the newer bodies they will have significantly more grip than if you are using the HPI bodies. The only possible exception is the Aero.

Actually you can tune the response of the car with the rim. Dish rims as a rule have less flex than spoked rims, except for example the Jacos which are very rigid. You can fine tune the reponse of your car with rim choice, but it is a very subtle tuning aid.

The Nemesis is also a very good body choice.

Is this how your modeo rear wing looks?
