I wanted to know what you actually gain [[and what is actually happening ]] from getting the brackets and moving the control arms???

Is this a Must with a LOT of power.. do ya think??

Thanks For any Info

Yes, its a good mod. Most stock LCA's either are level or angle upward towards the axle. When the car hooks, the body will push backwards, and if the LCA's are pointing up towards the axle, that will push the axle up and the tires will lose their grip. With the relocating brackets, the LCA's are now pointing down towards the axle. When the body shifts backwards on a launch, they will push the axle down, which pushes the tires harder into the pavement and giving more traction. Make sense?

Ya
Thanks Kevin
I want to get them from SPOHN and the LCA's
I was thinking that the adjustable arm's would be best as well as the Pan Hard

Did you have any problems with the Rear end shifting from either one side or the other as it sit's..after you installed springs and it lowered??
I think Mine has shifted towards the Driver side like an inch or so

Thanks again

One thing I noticed was my handling went down big time!

Stock, my rearend was all over the road, then I changed to ES poly bushings on the LCA and pan hard bar and I couldn't beleave the difference. Now my rearend felt super stable and I could take a corner with out getting that scary Four wheel stearing thing happening. But after installing the brackets and setting them to the lowest setting (most grip) I have to say my rearend feals worse then it did stock, very sloppy.

I guess you could look at this as good thing, it will keep you ziping around those corners. But with my new goodyear GSC tires my handling has improved and I could launch with very little wheel spin if any.

I'm not surprised. Best traction and best handling have different requirements.

You need to save that lowest setting for the dragstrip only unless you have lowered the car. What you get from the stock chassis height and the lowest relo bracket hole in a corner is a dose of oversteer due to the body roll. This causes the rear axle to steer slightly to the outside of the turn. Now you know what the NASCAR folks are talking about when they say the car is "loose". For the best handling you want the LCA's to be horizontal, not sloping up from the axle pivot to the chassis.

I have Steve's LCA brackets, on their lowest setting. I can't tell any difference in the handling, it is just like it used to be except the car has about 3 times the forward bite coming off a corner than it used to. Nowhere near as tail-happy under power.

I haven't noticed any disadvantages to them at all. I have the Spohn torque arm as well, the street version, and Lakewood LCAs. I opted for that stuff rather than the rod-end pieces, to keep the ride quality and avoid noise.

RB83L69 has a very valid point about ride quality. If you use the car every day I suggest you get at least one end of the LCA with a conventional style bushing. For best ride quality get both ends with bushings. Spohn does offer LCAs with one bushed and one rod-end or both ends bushed. If your car is almost all track then double rod-end is the ticket.

Hecubus, Lowering your car may slightly offset the rearend but not much. I use the adjustable panhard bar because the rearend in my RS was not centered from the factory. That may be the same problem you are seeing.

Well thats something that I have to think about then ...It's not a Daily driver but I do Like to take it out often and I love the way it handles now..

Would you go with the both ends Polly Bush./ or one end rod and one bush.????

because I do like to take it on the street fairly often
Thanks for the info guys

It s a tough call. I had the double rod-ended on my RS for a while and they were really rough on the street. I switched to double bushed and the ride was a LOT better. I would ask Steve Spohn about his that have bush on one end and rod-end on the other. That is what I want to try on the IROC but I need input from Steve as to the ride quality. In my opinion this is the best of both worlds, it gives you a bushing for isolating road noise and one rod-end to reduce or stop binding. Hope this helps.

hmm choices...heh

would you say that you were satisfied with the LCA's with the Bush. on both ends on your RS......as far as the preformance with the relocation Brackets??? Better traction

I think I might give them a try with the Relocating Brack.
thanks again

I like Global West's relocating brackets over Spohns, because GW's have a locating plate inside to firmly locate the bracket on the LCA mounting point, which SS's lack...

But its your call.

I run my LCA's in the lowest hole all the time. But I'm not a road racer so I cant feel the difference. I just know I get better hook that way.

 

Hecubus,

Yes the bushings on both ends are fine. The only advantage (in my opinion) to the rod-end is to keep the LCAs from binding while cornering. I think you would need a very trick suspension for this to really matter.

 

I'm with RB on this one. I run Spohn's poly/rod end LCAs, relo brkts, and street torque arm and have improved cornering performance over stock. I ran a set of poly/poly LCAs before the Spohn's and was extremely disappointed in their performance. The rear end would bind during tight and fast cornering, causing a hop of a few inches in the middle of a corner. Talk about cranking up the pucker factor... The poly/rod end combo cured this completely. Oversteer is not a problem on the lowest relo brk setting on my car. My corner entry and exit speeds have increased. I'm happy.

 

Mark 89Formula,

How is the ride and road noise with the rod-end/bushed LCAs? Is it as good as a double bushed LCA?

 

With no other changes, the LCA relocation brackets helped launches, improved cornering(especially coming out), and when it shifts 1-2 the tires just bark instead of spinning for 20 feet.

Chuck, no question that there is an increase in road noise and impact harshness over the double bushed LCAs. It's audible and detectable by the posterior. The bird was my daily driver until a few months ago. I was willing to trade the increase in NVH in return for the handling improvement. I imagine many people would not be willing to make that trade. The next time I drop the LCAs I'm going to examine the brackets, LCAs, and mounting bolts to see if an increase in bolt diameter would decrease freeplay.

As an aside, anyone who is interested in rod ends needs to know that they are wear items and must periodically be replaced.

 

Mark,

Thanks for the info.

 

What is the service life of a rod-end. Can you grease them?

 

That I would also like to know?

this is all good information ..I'm glad I asked

what is a typical life span??

The rod ends in Steve's LCAs are not greasable. A teflon coating is present in the rod ends Steve uses so I'm guessing that the need for replacement is driven by wear of this coating. Steve told me they would last "a year or two" in daily use. I don't know what that equates to in terms of miles but it's probably not many. I only have 3000 miles on my set and I think they've loosened up since new. I'd put the question to Steve over on his board for a more definitive answer.
