For lca's and the compliance bushings.

Ran hard race solid rubbers with me EK subframe, now i have urethane on my EG/DC frame. both had about the same wheel hop on the street..

If i switch to spherical bushings on front LCA's and the compliance bushing, will it eliminate the wheel hop? Mine is currently not violent unless it's on bad road. It hops a tad, nothing major.. Just looking to eliminate it completely.


Also, how do you clean out the bushing and grease it properly? The grease will attract more dirt and debree. Fuh do i do?

 

views and no replies?

 

I make these parts so I generally hesitate to respond because I am going to be biased. I use teflon lined (maintenance free) bearings so you should not use grease for the reasons you said. The grease attracts dirt which shortens the life of the bearing. Keep in mind that the bearing ball is primarily moving radially in relation to the race. Pulling a lot of dirt/debris into the teflon liner/race is not a problem that I or any of my customers have encountered.

Sphericals are 100% the way to go on a purpose built race car in my opinion and my customers don't have any appreciable wheel hop issues. But I don't like sphericals at all on a DD street car. Anyway, I am not at all a forum troll so I will stop there.

 

i drive my car occasionally on the street, weather permitting

will there be any discount from purchasing the LCA's with spherical bearings and also the compliance bushing? Do you have any distributors that can offer a better price than your website? I think these are the next on my bucket list to purchase

 

Contact RSTECH Racing and he can get you set you up

Didn't even know that this screen name was the one behind Kingpin lol

 

ChrisB / Kingpin Machine Makes an amazing product. Made my car go from 1.63 60 ft to 1.52 and zero wheel hop on a 24.5in tire.

 

Does Kingpin make a front LCA setup for an EK? I have looked through their website and have not seen anything for an EK. I have heard of people using and EG front LCA on an EK but you have to modify a little.

 

I'm just really starting to turn my car into a track "drag " purpose car. Looking forward to next year when I have the funds to redo my front end with the Kingpin setup.

 

As far as I know the straight part of the front LCA is the same between the DC/EG/EK. There are a number of EK guys running my LCAs. I don't convert the EK compliance bushing to a spherical at this time though. I would have to create a housing for the bearing since there is just that big rubber bushing and simple bracket on the EK. Unfortunately I don't own a CNC mill yet to make that housing. Just a CNC lathe.

Regarding the post higher up the page, my resellers are going to charge the same price as on my website. There is a lot of labor to my parts since everything is blueprinted and the bearings I use are not at all cheap. I am not a fan of sphericals on the street because a little compliance is a good thing over rough roads and high quality spherical bearings are expensive. But I have customers that do some limited street driving.

 

I cant wait to purchase a set of these!

 

are people are still running a traction bar with the kingpin lower lca's??

 

I have not and managed to cut 1.48 60's.

 

sweet

 

^^ told ya you didnt need traction bars with kingpin lca.

 

yah but most are not using an ef chassy, and like i said they have the rear factory stabilizers on the fronts but not the ef's

 

EF's need to run traction bars and i dont find it a issue...if anything it helps u mount different things like the radiator and also gives u the option to put weight bars.

 

Just echoing what j-bird said above. Don't confuse the EF and DC chassis issues. The EF is already a front triangulated LCA. So exchanging the factory crossmember and radius rods for a properly designed traction bar setup using 1 pair and only 1 pair of heim joints is a whole different deal from the DC/EG traction bar scenario. With the DC/EG chassis you are taking a rear triangulated LCA and adding on this extra front triangulation as a band-aid fix. Apples to oranges.

I do think front radius rod bearings in the stock front crossmember, stock radius rods and spherical front LCAs will work fine on track. But there are some inherent advantages to a properly designed traction bar setup on an EF.

 

thats on 26"x10" slicks?

 

Yes it was.

 

Norris cut a 1.43x a while back on a 24.5" tire. That is madness.
