In these conditions it's best to use a softer tire in the rear that can deal with the cooler temperatures.

Now when you say 2 shims front and 1 shim rear... what do you mean? I have an idea, but I want to make sure.

Also I run trailing front axle

That was what I thought you meant by 2 front and 1 rear. I am 2 rear 1 front right now.

Got a picture of your trailing front axles? I hate the axles that come with the kit. WAY too brittle. I spun out an axles while tightening the lock nut on it. I barely put my left nut into tightening these things and they spin out and not even tighten slightly.

Harry, try rollouts down to 55 mm. The car will really come to life for me with a 21.5 at around 56 mm. My rears are cut to 2.2. I run the Protoform Vette body and the car has no problems keeping up with the Mulsannes.

It is the axle in the kit
Can be set straight or trailing (offset)

Ahh ok, you flipped it backwards then.

I was hoping for an upgrade. Something in steel or titanium. Aluminium is not working too well for me. And with a LiPo car, I need something a bit heavier than Aluminium.

I just tried a Hpi Camaro.I like it alot.Better than the Firebird.The nose is lower,so there is a bit more downforce.I had to put stiffer front springs in the front.It has MORE stick through long sweepers.Good for long fast courses.

another 'realistic' zonda for you guys. I use this body when I race 27t stock class. It's fun looking at the faces of the people who race the blob/wedge bodies and wonder how I can keep up.

I like that, it looks good. You guys are running rubber tire, or are those on there just for show?

I switched the green springs to the front and red to the rear. Now it grips, and it steers beautifully. The Sophia GT body works a little better, but the Protoform C6-R Corvette body still dominates. When I didn't coat the front tires with Jack the Stripper, the Sophia GT was pushing way too much into turns. The Corvette was SOLID!! I coated the front tires, the Sophia GT was a little better, but still was pushing. The Corvette was much better since I could push into turns harder.

I am trying to wonder why the doorstop design was chosen. If it was to provide more downforce, I only see it in the rear. The front grip is vague at best. But as far as I understood it, and reading John Stranahan's post, don't you WANT a higher nose to provide better downforce for the front? And if the nose is low, shouldn't you use a front lip? I am not liking the Sophia GT body still.

I may try the Parma Aston Chicky Doorstop-9 next. Hopefully that body will provide better results.

Score: Scale "Realism" 2. Doorstops .5 (because of great rear downforce and adjustable wing position).

Between John's post on frontal down force and your testing, I'm sold too. Unless your running real high speed long straights the Sophia has no advantage. I'd rather have the steering any day.
