it makes the car turn real good
i think with a thiner t plate it would be to lazy.

uh,ok. It would seem you would lose your front suspension by going that thick. It would make the car extremely lazy. To each his own. I just never heard anyone ever run that thick. after 7000 wt i dont like the feel of it. This is any car i have driven.

Wally,

Are you serious?:weird: The front dampening works as shock oil does. You use this to keep the front end from over reacting. The reason we dampen the kingpins is to slow the reaction of the front end. There is alot less weight on the nose than the rear and the rear of the car react alot slower than the front. It is to give the car a good balanced feel.

You are correct with no kingpin oil. Let me explain. When you have no kingpin oil,the front react so quickly that it is hard for the front wheels to grip. The car has a hard time setting into a corner because the front will compress and then spring back too quickly. When you dampen the kingpins it will slow that down to help you get the front suspension working at the same rate as the rear. This allows the car to set and corner with the front and rear working at an agreeable rate which results in efficient cornering and carrying your speed through the corner. Now, when you go too far,You will start to run into problems with things such as oversteer mid corner or just flat out push because the the front cant dive and get the weight over the front tires.

There is a limit to every adjustment. If you get a chance try running 3000 on the kingpins. I think you will find your car working a little more efficiently:cool:

Hmmm... I never lubed the kingpin before because I didn't want to clean up the mess of lube and tire-dust. I didn't realise that it would have enough effect to make it worthwhile. I'm going to have to try it out now. One question though, do you have to relube after every heat, or will one application last 3 heats?

I have to say one good thing about racing oval is the oval guys come up with the coolest thing.

Like with make a new pivot ball with a groove in it to keep the keep more of the lube on the pin.

The part number is KSG2251 - Ultra Fr Pivot Balls W/Groove

You only need to use it on the bottom arm; you still use the stock on top.

Jake at JHP Racing has them in stock http://www.jphracing.com

It usually lasts the whole day. The area that needs it is the lower pivot ball. The rest is just overspray pretty much that doesnt hurt ya. Just try not to get too much under the steering block:cool:

Gen X Front end
 
Have any of you had problems with the CRC GenX front end breaking? There are a couple of guys (decent racers) who have had problems with breakage. One guy had to change his front end(not sure of the part name) 3 times last night.

Thanks,

Rob

Yea while I really like the design I've had alot of breakage issues. Now that has some to do with the design of the local track, here thay use solid 2X4's to section off the track. Those boards just do not move when you hit so all that energy has go someplace and I have broken lots of lower arms.:(

The new plastic ride height spacers that bolt up through the arm make a huge difference and if you add the carbon fiber brace it is just about bullet proof.

Are you talking about the brace that goes under the lower arm?

Never broke a part on my Gen X front end. I have bent king-pins when they weren't threaded in far enough, and have bent axles. Those are easy and cheap replacements. My biggest issue has been with blowing up bearings. I don't like the 3/16 x 5/16 bearings, the outer race is too thin and just breaks way too easily. I wish they'd machine out a new axel out of titanium to accomidate 1/8th bearings.

I may even try machining out some myself.
