Default Whiteline KCA375 Transverse Link Bushing Installation

So, who here has installed the Whiteline KCA375 Transverse Link Bushings. I have a set on the way, and was reading the online pdf which explains the orientation you use for the intall. They further go on to explain that if used in the maximum caster position, its possible that the "lower control arm fouling on the chassis rail." After looking at the photo in the installtion doc, i interpret this as the outer edge of the lower control arm rubbing on the frame. Alternatively, it could mean that the bottom side of the control arm may touch the USDM U-shaped impact brace. Has anyone experienced this behavior yet?

EDIT - Adding some installed pics:




this is the passenger side bushing looking towards the front of the vehicle.

You know, you're right! Now thre's a glaring oversite on my part. I'm curious why someone would add neg caster... unless to cancel out some oss cross value. I suppose its wise to warn about it in in case for whiteline as a CYA disclaimer. Thanks for pointing that out, Justin.

easy to get off and back on, find a shop to press in/out the bushing and mark the orientation/direction you want the bushings to go into the housing.

BTW, I have 4 degrees total with the bushings.

very necessary, the bushings are pressed in, it takes a ton (just guessing) or so of force to get them in there.

If you weigh alot, and your friends weigh alot maybe you can all eat a couple pizzas each then stand on them and get them in.

I removed some material from the washer because I was concerned about it hitting/rubbing on the frame. I just knocked off a bit for peace of mind. I used part of Cosworth's picture to illustrate.

STX illegal it doesn't say in the rules you can modify the washer

I was thinking of replacing my Energy Suspensions with these. How much *more* caster did you get with these bushings?

Every little bit is something... plus the hard duro bushing is great for turn-in crispness. But you probably already have poly in that spot, right?

Good advice, unless you happen to have a decent press at home. My 6 ton press BARELY managed to push the bushing out when I installed these things.

-Steve

BTW - I found a coupler for 1 1/2" OD steel pipe that was EXACTLY the correct diameter to use as a die for the press. It, plus a screw in cap cost me all of $4 at Home Depot.

Tom - I got .5 degree more positive caster as well. And the harder bushings do feel crisper as well. In fact, they have me wanting some poly bushings for the front LCA's as well.

Thats interesting... I didn't find any rubbing from the washer to the frame. The clearance was tight, but there was enough room. The action is not concentric and the washer is true and round so i don't suspect any touching to occur. I suppose that if your bushings were installed slightly off and rotated up some, you might impact the frame, but in the proper exact orientation, it seems fine.

Even though it's a stiff as hell bushing, I was still concerned with it moving a little and fouling up stuff, it was just a little close for comfort.

me too, where do I get some of those without buying an entire set of bushings of which I'll only need two.

I'm bumping this old thread because I want to understand exactly how these work. I had a local shop press these bushings for me and I installed them last night with the offset towards the outside of the car for maximum positive caster according to the instructions.

My question is this - how does moving the rear of the control arm towards the outside of the car increase caster? It seems like it would affect toe more than anything.

Also, I do plan on getting an alignment in a week or so, I will post the before and after results.

They move the wheel forward a bit and very much also affect toe (you need an alignment ASAP).

And this isn't an old thread, it's ancient.

^^^Thanks.

My car is not a DD, so it will not be driven until the day of the alignment.
