Jason,

For the upper control arms, is it necessary to puchase a new upper control mount or is the stock one ok to use?

 

I am still waiting on my Steeda Poly/poly adjustable arms to crack their bushings before I switch. Steeda even gave me a different set of bushings at the Mid America Shelby Meet in June, every time I jack the car up to look for damage I see a bushing that is just as new as the day I baught it. Maybe it is because we are running a stock gear but we launch hard (against the rev limiter 6800 RPM) and haven't had any problems yet, some increased noise over stock but I expect that. 1.65 0-60ft times even though they are poly set at the factory lenght.

If I were to buy new ones though I would consider the poly/spherical ones from BMR.

 

Kenny Brown's new K-Link Rear Upper Control Arm Module (KBP-28665) is even more expensive than Metco's fancy UCA...$399.95 vs ~$280!!!

 

Since you already have the Steeda ones why would you change
Steeda does have spherical ends available.

I would pull out the arm to check for distortion of the hole in the poly bushings.

 

Not sure why the Kenny Brown version is so expensive. I like the Metco design since it has a swivel that still allows the rear axle to articulate (probably a good bit more than a spherical bearing). Not an issue if you just want a firmer drag set up, but for autocross, road course or just rippin' around the local roads, the Metco design seems to be the best solution.

 

Steeda unit $179.00 works great

 

I have pulled them 8 or 10 times already, no change at all.

 

Yes, I can vouch for that. They have spherical ends available to replace the poly bushings on the axle end of the billet arms. They're not available for the chassis end so you would end up with a poly/spherical combination. Cost was verbally estimated at ~$50.00.
You would need a bearing press to install them I was told.

 

mmm, Metco.



JLT sells them now. I think the spherical ends on these are better for street use.

 

The Metco's have had issues with the poly bushings as well.

 

Every one that knows say no upper replacement required on street machine. Drag strip only' I was about to purchase the BMR one but did not after hearing this.

 

I wish someone would make poly bushings for the stock control arms.

 

I don't think it's all in the bushing. I think there's flex in the stamped steel as well.
I replaced the upper so that I could adjust the pinion angle. Of course changing the pinion angle is for optimal launch.

 

just bought my BMR LCAs from MAK Performance, cant wait to get them. $115, not bad!

 

They arrived yesterday, my LCA's and my UCA, cant wait to put these babies on!

 

I just ordered my LCA and relocation brackets this week What are those little things on the ends of the LCA?

Edit...thats where you can lub them right? They stick out more on a black one

 

what is pinion angle and how does changing it affect the launch? thanks.

 

Those things on the end are the "grease bushings", you use a grease gun on those "nipples" when they arms are on the vehicle to grease the inside of the bushings.

 

I prefer the traditional name: Zerk Fittings. Just has a certain ring to it.

 

Relationship of the pinion shaft to the drive surface the car is on. A correct angle will apply the rotaional power to the rearend more efficiently and therefore increase mileage, increase hp to the ground, decrease wear and tear on parts from poor alignment. I have adjustables and I haven't checked our pinion angle yet but it is important for all types of racing not just drag racing.
