Was wondering if somebody could explain to me the following in reference to the front suspension on an F1 car (similar design to a f104 or Sp-1 etc.)

Angle of the top arm - What the effect is of having the angle of the arm tilting forward or back?

Angle of bottom arm - What the effect is of having the angle of the arm tilting forward or back?

Distance between top and bottom arm - Effect of increasing or decreasing the distance between the arms.

Has anyone tried the R-Sector high traction system heavy rear pod setup?

I haven't installed the whole package, but it looks like there is a severe lack of oversight on the parts. It looks like they did not account for the offset and the edges of the rear pod are a lot closer to the left tire than it is to the right. And the diffuser is centered to the pod, but should be centered to the wing mount (true center). Same with the brass weight mounting points.

Its really ridiculous that they designed it in such a way and didn't fix it. (Or look at it carefully during the early design stages.) Anyways, just ranting and warning potential buyers...

Angle of the upper front arm determines the amount of reactive caster. The more the upper arm is angled forward the bigger reduction in caster occurs when the suspension is compressed.

Angle of the lower front arm does nothing on most F1 cars. This only has an effect on double wishbone front suspensions like the aftermarket front suspension for the 3Racing F109. On cars with that type of suspension angling the lower arm backwards increases anti-dive. Dive is how much the front of the car lowers under deceleration.

The distance between and the angle of the arms effects the cars roll center.

"Upgraded" my F104v2 with the Rsector Wide Track Conversation Kit today. It was a little painful as it wasn't the drop-in I expected. The first "surprise" were the missing M3 threads in the steering blocks for the ballstuds. For the left rear the F104v2 owner also needs a shim tube. Luckily I had one from my F103GT rear axle conversation I did last year. The rest of the installation went as expected and makes the car look better.

Now I am looking forward to the laptimes. Last race my car dominated even the 200mm F103. So I am not sure if 190mm will make the car faster than it was with 180mm. How are your experiences on an unprepared, grippy asphalt track?

I think you will like the feel of the wider car. I am looking forward to hearing what you think after driving it.

The problem with the rsector widening kit is the tyres at the front are moved away from the steering pivot point. This makes the steering quite sluggish.

It will add a bit more stability, bit similar to running the offset Exotek wheels. It will also get awfully close to the F60 front wing side tips, something to keep in mind. My only gripe is it is inline axle only. There is no option to run it trailing setup. I am running the stock F104 arms. Although with the Exotek arms, you can still play with caster. Just depends on your preference.

I am going back to the narrow setup and trailing axle setup. Removing the R-sector wide kit off the car.

The fusion is about to commence.

Thought I would share what I consider to be the proper way to widen the F104.. The set up is slightly different because I use a Exotek F1R2. Car is 10mm wider at the front as a result and using the rsector widening kit to widen the back. Result allows for a more stable car with higher cornering speed but a lot less compromised steering response due to retaining the pivot point at the same point as the standard.

It's a prototype I had made up. Just working on better understanding the benefits and how to tune it to gain more from it. Had my first race meet with it and it worked quite well. Though it was at a track I've never been to before so I don't have anything to base the performance on. Hoping in the next few weeks to run at a familiar track to build a comparison.

I'm wondering, is there any reason apart from simplicity that there's so few double wishbone front suspensions on F1 cars?

I was looking for a decent front end for my F104 and couldn't find one that'd tick all the boxes for me so I'm tempted to build my own, but I'm not sure which route to take (double wishbone vs. solid lower arms vs. solid lower+upper).
