Mancini Tubular uca's

[black71]

I have dealt with mancini racing several times and have been very satisfied... i'm looking to get tubular uca's and was looking on their site. you can upgrade to heim joints and i was just wondering if heim joints are good for street car use?

[Chryco Psycho]

they are very strong & as long as they are kept lubed I do not see a problem but there is not dirt seal for them

[black71]

so would you suggest just regular poly bushings?

[black71]

what about reilly motorsports arms? ....sorry... i'm so indecisive

I have not used either yet ,we used rod ends everywhere building racecars, they replaced tierod ends , they were used to hold the diff in place either on 4 links or ladderbars , if they failed the car would be thrown immediatly sideways , but they pass at the track on 200 MPH cars , but while they are strong they do not take the miles a street car woudl , although I have used ladderbars on strret cars & have never had a rod end fail

I wouldn't recommend heim jointed suspension parts on the street unless you really don't mind the constant rattling ride. They have absolutely no give in them at all. While this is great for a performance application, it may be a bit much for a street application.

There are seals out there for them, if you choose to use them. http://www.speedwaymotors.com/p/1528,107_Rod-End-and-Heim-Joint-Seals.html?itemNo=heim%20seal

As far as the different manufacturers, chose one you've had good results with. Honestly, there is not a whole lot of difference in how you make a tubular control arm. There are only three parts to them. Except for one style, they are very similar. The only one that is really different from the rest is the Magnumforce double adjustable units, which can be adjusted on the car. All others require you remove the arms to make significant adjustments outside of the normal range offered by the eccentrics. However, at $400 a pair, they are pricey.

Heck, IMO, $300 a pair is robbery. There isn't more than $150 worth of material in any of them, and there certainly isn't $150 worth of labor in putting them together. But, that is just my opinion. They do offer an improved range of adjustment and lighter weight and increased strength, which are all good things.

i agree i just called a bunch of places today about them the magnumforce units are nice but 300 seemed a lil $$$ and just suspension ones look good too there solid metal not just a tube but their 400 and since my threads are stripped on one of my A arms i need to get something

[black71]

hmmm thanks for the info guys.... i really have liked dealing with mancini, they always get my parts to me fast without any conflict.

I road raced with stamped steel a arms, and then switched to the tubular arms, since they are much stronger , and i was able to attack the same apex much tighter , in other words the car was able to turn into the apex much sooner, with the stamped steel a arms, there was enough flex that i could feel the alignment start to change, with the tube arms there wasnt much flex, in my opinion, 400 bones is alot of money but these cars are worth 50 grand plus, and this mod not only is stronger, but lighter.and lighter in the right place on top,and its unsprung weight almost,and i felt the car was more nimble in a chicane ,back and forth, they are worth it to me but i turn corners hard on a track, and on the street they along with the heim joints ,are a little overkill just my 2 cents worth

[black71]

my stockers need replaced, one is bent way out of wack..... and i was going to do it for the extra caster and added stability with power steering

[black71]

sorry my last reply may have seemed a little snotty but i didn't mean it that way thanks for your opinions guys i do really appreciate them all!
