Default retrofitting Active Handling in 97-99 model

Hi all,

I'm in the process of buying a C5 and got offered a pretty interesting deal on a '99 coupe. The problem is, it does not have the JL4 option (Active handling). I want to drive the car in the wintertime also, so I would like to have that option.

Now, is it possinble to put that system into a C5 that didn't came with this option from the factory? I've searched the archive but couldn't find anything.

Does anyone have a parts list (maybe with part# and prices) so I can check out how many parts are involved. I know there are a couple of sensors and some brake hardware.

I'd be happy if you could help me out with some data on this issue. I just want to see if this would be an option or not, otherwise I would pass on that car.

Thanks,
Alex

I think retro-fitting will be very costly. You're better off finding a car with that option if you really want it.

However, if you choose to buy the car at hand, you'll still have traction control - that's more than enough for driving in the winters. I personally have my reservations about the GM version of "Active Handling".

This topic has been discussed before. Might try running a search in the C5 section and see what you get. I would guess it would be much more costly to retrofit than to just buy a car with the system.

You would need to change the EBCM and probably the BPMV which would run you about $1700 for new parts ($1200 if you could get a deal) but that still may not get the job done. The forward wiring harness would probably also have to change plus you would need a brake pressure differential switch and other wiring changes in the cabin. Cost isn't worth it.

You would be better off looking for a car that has the option already.

As for the snide comment about the GM active handling system it is the only world class system in the world. Even the early system (pre 2001) used better algorithms than any of the other manufacturers used and in 2007 they still haven't caught up with the early system let alone match the newer one. Even the car mags talk about how well it does its job compared to the others.

I have to say it saved me once. And that wasn't even pushing it; just a 270 off ramp that caught me out.

with Bill. AH is a great system

Well I'm glad it works for you all. But I've had it activate for no reason whatsoever while traveling at 70+mph on a slight decline and it almost sent me into a wall. That's what I call "World-Class"
