Mate, I was considering a micro servo and push/pull wire setup for proper DRS, use it with the third channel - just to mess with your head !!

Mine actually started to spark a bit while testing yesterday (was getting dark outside)... My first thought was that's so cool... Then I stopped so I wouldn't damage the car.

Still haven't had an answer to my front end ride height question, I can't see how I can get more out of the front.

Running outdoors on asphalt you eventually just get used to the chassis getting scratched up. Some people will use a chassis protector sheet underneath but that becomes a bit of a hassle and most people give up on them. Also keep in mind a lot of these setups and stuff you are seeing mentioned is for indoor carpet which is much smoother so lower ride heights are possible.

What is your front end question?

You're right about the carpet being more forgiving but bottoming out the chassis is never good. I'm actually running 6 to 7 mm all around and the handling is really good. Nothing unexpected from bottoming out either.

There's always a trade off between bottoming out or raising the chassis. As you raise the chassis the car has a much higher roll tendency so often you will actually get better performance even when the chassis bottoms out. Most of the bottoming out issues on asphalt have to do either with a bumpy track surface or from crashing the car. Neither of which is going to have an impact on the car's handling. Watch just about any full sized road race at night and you will see sparks from where the chassis bottoms out over the bumps...especially in classes like F1 where they actually have to regulate how much wear is on the board under the car or the teams will wear it right out due to their low ride height.

What's the highest you can set the front end ride height. With the two shims between the knuckle and the upper arm the car is at 4.5mm. But I can't see how I could fit more shims in to get higher.

The fgx has a low roll center up front and it is too low for high bite carpet. Since there is little adjustment up front I had to max out the front ride height thus raising the roll center to keep from traction rolling over the front end. With a high front and a low rear the car pushed really bad so I raised the rear to get front traction back.

I also was bottoming out in our sweeper and the car was doing some really wierd handling tricks so for me the raised roll center and chassis helped a lot more than the occasional chassis scrape.

I guarantee the full size race teams are concerned about bottoming out. Any time you hit the chassis and take the load away from the suspension it causes handling problems. They are not ignoring the occasional scrape. The goal is to maximize handling while minimizing ride height without scraping although they do occasionally scrape.

I was able to run 3 of those shims on top just haha but 2 1/2 of those shims would probably be better

Wow, cant see how. If I use 3mm worth of shims, the top of the kingpin is level with the top of the ball joint thing in the upper arm. 2.5mm I cant get the E clip on, but nearly....

What am I doing wrong?

I didn't say they weren't concerned about it...I said it was a trade off...or a compromise. Often times they will trade off some amount of bottoming out for some other performance advantage.

My earlier point being...running on asphalt the chassis is going to get scraped. Raising the ride height just to protect the chassis will sacrifice a good deal in handling because either bumps in the track or accidents/collisions will cause the suspension to compress more than normal and the chassis will scrape. Most of us just get used to it and tune the ride height for handling rather than for protecting the chassis.

Agreed. Maximum handling is the goal. I have just run into too many people that will slam a chassis just because they can. Lower isn't always better. Just wanted people not to be afraid to raise the chassis and try it out.
