I'm looking to purchase some new goodies to help me do more work by myself.

First up - a set of corner weight scales. I've read the one thread on here about someone who has them, but was wondering who else has used a set, what brand(s), what you liked/disliked, what features are handy vs. what's not worth the extra money.

The ones my brother and I have been looking at are the low end models, as we don't see the need for something really fancy. Everything will be kept in an Excel sheet for each session on the scales, so I don't feel I need a memory function. I also have a spreadsheet to do a lot of the calculations that the higher end units do for me, so no need for that. I don't see the need for wireless, as it just seems to add a good bit of money, and I'm ok with running wires, unless someone has a good argument for using a wireless kit.


And what kind of accessories make working with scales easier? Levelers, roll offs, ramp systems, etc.

We have been considering Hubstands (seen on last tab in the spreadsheet linked below) because of the ease in setting the weights. You can easily get to the suspension without having to unbolt the wheel every time you need to make a change, then bolt it back on to see if you changed it enough. Anyone ever use these, or at least have an opinion on them?



Next - alignment tools. I'm looking for some tools to do camber, caster, toe, and possibly bump steer. Same deal as above - what have you guys had experience with?


The two major brands I've been looking at for this stuff is Longacre and Intercomp. Longacre has a majority of the alignment tools, along with scales. Intercomp only has scales. And I know Rebco also has an economy scale model, but I didn't really look into that too much.


I don't have an unlimited budget, but am not looking to skimp on these purchases. Here's a spreadsheet that we've come up with that has all the tools each company offers. We've highlight parts we think would be good, and not be overkill (both in features and on my wallet).

Suspension Tools
 
I've used a set that I rented from a friend, Longacres IIRC. The set I used had wires, not a big deal outside of the minor pain in the arse to unwrap/wrap them. Wireless might be worth it if one were to use them a LOT.

The LCD readout in the one I used, calculated the corner and F/R percentages, nothing more, I didn't have a problem with that.

The hubstands would be sweet, I suspect. It's a pain adjusting preload with short travel coilovers. Not a lot of space between the fender and tire, even when raised. I was able to access the preload collars but it was way awkward. I thought of making a set (hubstands) for my car shortly after doing all of this.

I have no experience with any of the other stuff. Most race teams seem to have all of these bits at the track but they usually have sponsor money and all.
 
I have two good friends and one uses Longacre the other uses Intercomp. Put simply Longacre is club-racer level while Intercomp is professional level.
I have never seen the Intercomp use hubstands, but you can't go wrong. Those are sweet and would make life easier! I don't know about the leveler, but I remember seeing him just using a 3' long level you can get at Home Depot to make sure the scales are all level. I also want to suggest the Smart Camber Gauge and Smart Strings. Those are two things on my list. Hubstands can wait. :)

Looks like my favorite local race shop uses Hubstands. I will have to investigate more. :)

Could you please expand on this?

Just the fit and finish. Intercomp was all CNC'd billet- it was gorgeous, but it cost more than Longacre. Longacre was like stamped or press-bent stainless steel. Both do the job. After looking at Intercomp's website, the cheapest scales are a little more than cheap Longacres. If you can afford the extra money get Intercomp.
Sax or Snowboarder, if either of you come out sometime I can take you by 3R to see their shop. Also, my Atspeed friend will open his own race shop in July, I'm sure he could 'brainwash' you into thinking Intercomp is the best too. ;)
 
I was out there not too long ago and met up with Chris. I'll be back out at some point soon, so I'll let you know when as well.

Aluminum squeeze casting is what a guy at Longacre told me about the pads (called in and talked to someone). He mentioned that cup cars use these (at 3400 lbs.) and they see no to very minimal flexing of the pads. The fact that they do sometimes see it kind of worries me a bit. Not sure if the billet would help in that case or not.

They still sell more wired than wireless, and the only difference between the Basic and Semi-Pro models is the 4 line display and memory (the big thing that raises price). If we use Excel to track like we plan on, there's no need to get the higher model.


Edit: Also called 3R just to see what they said and the guy seemed a bit confused as to why I was calling :p He said their suspension engineer recommends the Intercomps and feels they give him the most precise readings. And he was very vague on the alignment tools.

Just let me know when you are here. The guys that work in the office are nice but not as personable. Intercomps are gorgeous, I remember the first time I ever saw them, I was blown away. I honestly think if you got Intercomp you wouldn't regret it.
 
We'll also take suggestions on bump steer gauges if anyone has a recommendation. I'd really love to see how the bump steer is at stock ride height and lowered, then have the fun of designing a way to fix it if needed :)
 
Attached are a template of the Excel spreadsheet used for corner balancing and alignment, as well as an example of it filled out from Brian's car.

It’s pretty specific to the set of tools we’re using, so you can just pick out what you might want to use in it. Let me know if you have any questions.

This might seem like a dumb question, but I have to ask because I know my wife will ask me: how safe did you feel climbing under the car when it was on hubstands?

I know I'd feel a bit better if the bases were just slightly larger. But really, I'd be surprised if a football player could knock it down/destabilize the feet enough for the hubs to rotate and allow the car to come crashing down.
 
Have you seen Iowa's defensive line this year? I don't let those guys near the Evo when it's on its wheels, let alone hub-stands.
 
We use longacre on our FSAE car, its only 500lbs. Getting the pads level is the most important part IMO. I would suggest ramps for sure we have a sset and they are very nice to have, just roll it on and off.

Flash, do you work for 3R?
 
I felt perfectly safe under the HubStands. I was nervous setting the car down at first, but they took it no problem. They're beefy.

No need for ramps, the HubStands take care of that problem :)
 
Bringin' it back,

Did either of you notice any driving impressions with the extra caster? Driving around with just a bit of camber and no toe isn't a big deal but I've not thrown this much caster at it before. I'm reserving any judgements until I get aligned tomorrow but just driving it to my lady's place left me with the impression that steering rate has decreased and/or even uhmm.. can I use "amplitude" here? "throw"? How about "total steering extension". There, that sounds nice.

Anyways, I think you'll get the jist of what I'm trying to say.

Honestly, I haven't driven my car since before I did this. My brother "limped" it home, seeing as we haven't installed bump stops yet. I may get to taking some measurements this weekend if it's not too cold so we can get spacers cut and installed, but sadly it'll be a while until I can get some good data/feedback on the alignment change.

Eric's car is still waiting to have the suspension installed.
 
I see for your final alignment specs you have 6.0 flat for caster on each side. Did you leave the plates set to max, or did you have to adjust one side to get the values to match?

Today I was granted 5.8* and 6.5*. I wish that driver's side was a 6.0 flat. Things like that please me.
