Delta VS Radius Arms (7 Viewers)

Understood. Guess I should have asked how many pre-orders you currently have for the 4".

Have not opened those back up for ordering yet, have to get the stuff figured out to make sure everything is working on the back end of the site for pre-ordering them.

Just preordered a set of the new Delta 3 arms.

Compared to the not in stock Delta 4 arms are we just looking at less caster correction? My only concern right now is everyone seems to think more caster is always better for driveability, will we be missing some amount of improvement going with the Delta 3 arms vs 4?

Caster for 3" arms is ~1.5* less than 4"

The driving forces behind this update are:

1. Literally every single day I get communications asking "I have 3" lift, do I get the 2" arms or the 4" arms"?
2. Reducing the number of parts we have to keep on the shelf. As noted, we will still make the other sizes. We just don't have room to keep that many large items in stock ready to go.

I feel like I've read this somewhere before.

I'd bet good money you'll hear it again

Not a bet im willing to take

Would there be a significant expected driving improvement with the additional 1.5 degrees?

Unfortunately that's going to be a really hard question to answer, as it is much more of a personal thing (from talking with many customers). Is your "other car" an Audi RS6? If so, maybe every little bit will count and help get you that stable feel. If it's a 67 split window VW bus, you probably won't notice the difference in 1.5* of caster, unless it's going taking it from positive to negative.

When caster goes from positive to negative, physics takes over and the ground goes from pushing the wheels back to going straight, to the ground trying to make the wheels turn.

Funny you mention that, other car is a NSX. I'm not looking for sports car like feel but as much improvement as possible would be great. Right now it's incredibly tiring to constantly be correcting the steering on the highway and under braking with the tires following ruts/etc.

Caster reading right now is nearly 0 from the last alignment, Running OME 861 front 863 rear (medium 2.5" I think??) and the OME correction bushings...

Should I switch to the 4" arms and just wait it out for the group buy limit? (Sorry to be asking the same questions as you've been dealing with on the daily)

Currently no driveilne vibes at all, if I understand correctly the only possible consequence of going with Delta 4 vs 3 is potential for driveline vibe?

uhhhhh, you trade arms for NSX?? That is my other dream car (80 was first).

If you're close to zero right now, 3" arms will put you over the stock spec, so I wouldn't choose 4" arms.

He's close to zero, but he ALSO has the OME caster bushings installed. That's WITH the bushings installed.

That's close to 0 WITH the OME correction bushings.

Missed that part of the equation. Those are SUPPOSEDLY in the 2-3* range, has not been verified in this shop. If that's the case, 3" arms will add ~6*, so should be just fine.

 

[unclegit]

That's close to 0 WITH the OME correction bushings.

Ditto - I ended up deciding to wait on the 3" arms at standard length...

From my numbers 2" was on the lower end of stock and 4" was the higher end of the stock range... 3" was goldilocks - happy to give feedback once I get em on and the truck back on a rack.

The other car is a supercharged lotus exige - so I'm expecting big things

My only thought/concern was it seems everyone agrees that with larger tires (I'm running 35s) the consensus is higher than the stock 3 degree spec is better for driveability, with the tradeoff being potential for driveline vibes. Seems we are going to be some of the first running the first batch of 3" arms so we'll have to see

Sweet Exige btw!

Just a quick note: ALL of our arms are designed to put caster to +4* at the stated lift height.

@Delta VS any rough ETA when the first batch of 3" arms will be shipping out?

post #383 of this thread...

but they are at powdercoat. once they get back from there, all packaging is prepped, etc, and they should hit the road pretty quick.

thanks DVS

got my 3" arms in the mail, installed, aligned.

caster sitting at 3.4 deg on the driver's side and 3.7 deg on the passengers side. car tracks much straighter now and i can finally relax on the highway.

for reference, I'm roughly 22" center of hub to flare in the front. Back may be ever so slightly higher 22.5 or 23

How tight is the clearance between the arms and the trailing arm on the steering linkage? I ask as I recently updated to Marlin Crawlers HD setup. I’ll likely be in the 2-3 inch range.
