Spring Rate on Coilovers

Does anyone know the factory spring rate/lbs of the factory coil over springs?

I can’t believe that car weights 1000 front and 1000 back -

Looking for some replacement coilovers, I went with 150lbs on my Slingshot and it only weighs 1650 pounds.

I am sure summit racing has something, I just need a place to start.

I can’t answer your question other than to say that I think you could replace them with steel rods and it would be softer. :frowning:
I just purchased a set of air shocks off of an old Goldwing to try out. I’m told they work great with a lithium upgrade which I’ve just finished. They’ve been reported as being a bit too soft for cars running lead acid batteries. This all applies to the pre 2005 cars of course. Not sure what year you have.

@Mr.Vern
It’s a 2002 and we just did a Lith upgrade from Dave the same time you did :slight_smile:

Let me know how the Goldwing shock work!!

Have you gotten your car to run at over 95.9V? We get a 77 error code anything over that voltage. Anything below that and she runs like a spanked ape.

I haven’t gotten my charger from Dave yet (expecting it any day now) so I can’t charge above 91V. My car runs amazing with the pack. I still haven’t installed the shocks yet because I want to get done with everything else on the cart before I start another project. My whole journey started because I had limited range. The Volt packs fixed that. However, I had a noisy bearing so I took the motor in to get it checked out and found out that it had a shorted armature winding. I am getting my new motor tonight and can’t wait to see how it runs. I’ve never driven the car without the bad motor and the lithium pack gives me great range even with the shorted armature so I can’t wait to see what it does when fully charged and in a goof motor.
I will probably get around to the shocks next week as I’m out of town this weekend. I will certainly let you know what I find.

@MikeKC
That’s a good voltage for long life. 4v/cell.
You can easily tap the modules back one cell for 3.7v less.
It’s diminishing returns however. Gain a few wh by higher charging, but lose 300wh having fewer cells in use.

@Inwo
We will be right in between running at 93.3V or 3.88 volts per cell, should work fine for our needs. Plenty of range and batts’ should last a very long time.

@MikeKC
I got my charger from Dave and charged to 95.9V with no problems. I decided to test the higher voltage and took it to 96.8V today. It powered on and moved in my garage with no errors. I have a T1 in that car. I’m not sure how high I can go before I have a problem. I am using the 15V spoof of course.
I still haven’t installed the air shocks yet but will report back when I get done

Interesting information, we have a T2 and 96 seems to be the cutoff. Interested to see how hight you can go.

and the shocks of course :slight_smile:

What I do get is error -76 when I lift off the throttle. I’m going to disable the regen and see if it stops. I suspect that regen is tipping me over on voltage when I’m fully charged. I blew another seal on the input shaft last night and I have to fix the oil leak before I can do any more testing. It’s the second seal I’ve lost so I’m not sure what I’m doing wrong.
I also have a car with a T2 so I’ll do the lithium in that next and see if I run into that limit on it.

Is your gearbox vented? Early cars weren’t.

Yes, it has the white vent tube on it. I wonder if its plugged. I had replaced the shaft with the kit from Richard per your recommendation and my helper put the seal in backwards. I ordered the seal off of ebay that you pointed me to and now I have a leak still. I haven’t installed either seal personally because my helper is an experienced well pump mechanic so I assume he is more capable than I. I suppose its time that I look at it personally to see if I can spot the problem.

@MikeKC, I still haven’t duplicated your 95.9V threshold with my T1. However, yesterday I discovered that on mine if I change field 15 (Battery Voltage) in my controller with my programmer, that it shifts the high voltage limit and I don’t need the Voltage Spoof. I’m thinking that it probably shifts the threshold you have run into as well. Do you have a programmer to test it? I’m charging mine to 97V right now to see if I can duplicate your experience. So far up to 96.2 I haven’t seen the problem you have.

Well, we definitely have the issue with a T2 controller, overcharged yesterday to 97V and no go…

We do not have a programmer but Dave has a new BMS on it’s way to us set to 95.5V’s so we should be fine after that.

Any luck with the shocks yet?

I’m hoping to install the shocks tomorrow. I’ll let you know the verdict when I’m done.

This is a great forum, I have a lot to learn

I’m Intrested weather you can get a T-1 or T-2 to accept a Higher voltage then 96-97 volts.

Dave seems to think the controller senses voltage from more then 1 location. Example other T-4 controllers sence voltage from pin #1 and that where Dave’s voltage spoof fools the controller. On T-2 co trollers we think it senses voltage from another source as well that we can’t spoof. Bummer!!!

@grantwest I’m pretty sure you posted your comment above in the wrong thread ^^^^^^^^^^
