did you not use ford uprights on your truck? I don't get why you'd have to ream.


FYI there's some Ford mustang adjustable heim shanks with 7 degree tapers on the internet. Don't buy them. They're the right taper but the diameter is too small to fit in the evo upright.

 

Built new ones. Stock cast ones with stock wheel bearings aren't the greatest at holding a 35" tire on the truck at speed in the desert.

 

Does anyone know what the added caster of these would be with just the LCA from an x on an 8/9?

I have the Perrin PSRS, I'm gathering that I couldn't use those on the X LCA since it'll push the wheel too far forward..

I'd like to know if these LCAs push the wheel forward more, less, or the same as the PSRS. Eventually my Perrins will wear out and they don't make them anymore so I've been looking for a fix to that. This seems to have a few other benefits to it as well..

 

pretty sure both arms will create identical caster stock for stock.

Perrin PSRS part numbers are identical for 8/9/10.

Same for whiteline RCK

 

I think his question was this: Does the X LCA, by itself with OE bushings, add caster to a CT9A? We know they're wider but is the balljoint pushed forward at all?

Danny, you still have your X LCAs? I have a CMM arm here at work and we can get measurements on my VIIIs vs. your Xs.

 

Anybody know if the x and the ralliart use the same lca?

 

Correct.
Someone mentioned the X LCA s adding some caster when installed on a CT9A. Just wondered how much it would add or if it's even verified.

 

Yup! i Sure do still have the LCA's. They have the psrs and whiteline RCK pressed in them though, but they still should be able to do what you're looking for.

According to this link, an X has 1.5 degrees more caster than a 9. We don't know if that comes from arm placement or strut tower relocation.

Nope. RA is stamped steel and different geometry.

 

I'm 90% sure what I was seeing was not stamped steel. They looked like 8/9/x arms but slightly thicker, I assumed the stamped steel ones don't look remotely equivalent.

Either way, after like 3 months of searching I snagged a set of x arms off eBay of all places this morning. Gonna use the superpro offset rear bushing and potentially a hard race spherical front (discussion of spherical install in another thread has me a kind of leaning back towards poly tho).

Hopefully I'll not only get the extra track width but I'll get back some of my missing camber

 

I'm 100% sure they are steel. They are not forged aluminum like the Evo.

I owned a RA for a couple years.

 

The 2011-2014 Subaru STI Perrin PSRS bushing is identical to the Evo piece - you can still get either offset or not. Perrin just no longer supplies the spacers that go with the kit.

 

Razorlab is absoustely correct, Ralliart arms are steel, upright is totally different from Evo X upright.

The caster- I do not believe the Evo X arms add any caster to Evo 7-9: any added caster in Evo X must be coming from top mount!

I now because I use Evo X arms.. and with Offset PSRS/Caster Top Mount at max caster I am still at only 5 degrees of caster circa, depending on rake of the car.

 

I think you are correct in your assumption. THe PSRS kit only adds .5 degrees of caster over stock.

 

I called Perrin and they confirmed this. the 2011-2014 sti psrs is identical but comes with different spacers. Why perrin decided ti was too much trouble to machine a few spacers is beyond me. I honestly don't think perrin designs very good parts. They need some legit engineers on staff.
