Pictures? Air lift / StanceParts

[PaulProe]

Does anyone have pictures of the front coil-overs with the StanceParts AirLift installed on an RCR GT40?

I am told by some they don't fit, I am told by others they have them and they work fine. Don't know if it may have been a singular build issue or if the builders had to make modifications to make them work. A picture is worth 1000 words.

I have pictures of them installed on a GT-R and a SLC, but those are different frames (but similar)

Can anyone help?

I tried the Stance cups but the interfere with the chassis. If you flip the shock they interfere with the upright. Same issue in the rear. No pics with the cups but here are a few showing the tight clearance. I’m not aware of anyone installing the on a RCR GT40. The cups are 4.75” wide.

I should be receiving my RCR40 kit this month. I think it will arrive with the airlift shocks mounted. I’ll let you know if there are interference issues.

Stanceparts also offers 110mm cups. Did you raise this question to them when you made your initial purchase or when you ran into issues?

The ones that I have seen on a SLC did install the shocks with the rod down and the cups on the bottom/upright end.

They were not available when I purchased them. 110 may work. Interested to see Randy’s setup.

I finally received my Stance lift kit. The cups are indeed 120mm. They will definitely interfere with the chassis.

I am going call Bill at RCR and ask what they do. If they don’t have a solution I am going mock up some 110 cups to see if that will work. The 120s might fit mounted on the bottom of the spring, but then will fill with debris.

If the 110 mock up still doesn’t work, then I might cut a recess in the tub and fab a pocket. However, I am concerned with interfering with the pedal assembly.

The 2 gal tank is going to take up a lot of very precious space. I see in the Stance manual that the pump can used without the tank. That is probably how I will install it, or I might look for a one gallon tank.

I talked to Bill at RCR. He said that they put the cup on the bottom of the spring and that they haven’t had any problems with debris accumulation. He also suggested getting a one gal air tank. I just ordered this one. It has plenty of ports and is currently on sale.

You might check for interference with the upright. Neil reported he couldn't get it to work. Don't know what the issue wasyou

If you can, post a picture of it mounted on the bottom. Maybe a shield to deflect stuff going to the cavity?

Paul, I hope to do some clearance testing tomorrow. I’ll take some pictures. Closing off the cup is a challenge since the spring has to be able to compress. Perhaps a nylon sock with a hole for the coil. I am going to call Stance to see if they have any ideas. Cheers, Randy

Below are pictures of the 120mm Stance cup in both right-side up and up-side down. It appears to have sufficient clearance in the up-side down position, not possible in the right-side up position even with a pocket in the chassis because the upper ball joint nut on the inside of the control arm will catch the edge of the cup.

I think the 110mm cup will work as long as the spring tension nuts are set to the bottom of the shock and a spacer washers are used at the top of the cup. Might still need a small pocket in the chassis.

I sent a message to Stance asking if the 120mm cups can be exchanged for 110mm cups. I don’t expect a response today due the time zone difference.

 

[Randy Folsom]

I mocked up a 110mm cup using a yogurt lid. It will not work in the upright position without a pocket. With the 110mm, a 10mm deep pocket by 2” tall and 3” wide should be enough. The 110m does clear the ball joint stud and nut on the inside of the upper control arm. The 120mm cup will not clear the ball joint stud without trimming the stud. Not something I am inclined to do.

So now I wait for a response from Stance. If the 120mm cup can be exchanged for the 110mm, then I will fabricate pockets, otherwise I will use the 120mm cups and install the shock upside (rod) down.

Perhaps a 1/4" spacer for the upper shock mount.

Perhaps a 1/4" spacer for the upper shock mount.

I did test that. Because the shock is near vertical, it takes a 1” spacer to gain 1/4” horizontal clearance. The spring nuts provide 3/4” space when lowered to the max, not quite enough.

Randy,
Just thinking out loud with some ideas

• They seem to make these work on the GT-R and SLC models. Looking at the pictures, it seems the upper shock mount spaces the pivot out a little further from the chassis than as is used on the GT40. If you go too far, you run into interference with the control arm. Without a chassis to measure, I don't know if there's a compromise
• Maybe using the 110 diameter with a upper pivot spaced out?
• You might also gain some clearance if there was a shorter spring and a spacer to move the hat/cylinder down away from the pivot.
• if mounted upside down, what if you carved some foam to fit into the cavity of the spring and the ram. It wouldn't keep water out but it would keep the big chunks out
• QA1 makes a shock extension and used to make a 'long reach' upper eye. But either would require a shorter shock to fit the application. I don't know the shock size or spring length so can't theorize much beyond that.

I am kind of surprised that others haven't chimed in with a solution, you can't be the first person to do this. What are we missing? Hoping some of the other RCR owners/builders who have used these will chime in.

Paul, you are correct that moving the shock mount out would result in hitting the upper control arm, specifically the ball joint stud and nut. The top of the cup can be moved down about 3/4” with spacers on the rod end, but my crude measurements indicate that the 110mm cup will still need a small pocket.

I like your suggestion of filling the inside of the spring with soft foam to minimize the debris collection. It would also wick away water.

Cheers, Randy
