Coilovers for GT350?

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others.

Looking for feedback on coilovers for the GT350.

If or when SACHS offers the same setup they have on the FP350S, that would be a nice option. I see that MCS Motion Control Suspension, Tractive/Coretex and Penske are currently available.

The reason I'm looking is because the Magneride electronics on my car is not working. I realize I will need to figure out the Steering and ABS functions in order to go this route.

Filip at Cortex is your best option. He’s already done GT350’s that originally had magneride.
If your magneride still isn’t working, something is missing from the system.
It’s either in the harness, ground, or something that was eliminated.
Has Capaldi not found anything yet?

I would agree that CorteX will have a very capable offering based on their direct experience with the GT350/S550, especially for a race-focused application.
 
Several companies offer a system for around $700 to “fool” MR. not sure what I will do yet.

Gotcha. I know DSC has a module that works with (not entirely deleting) the computer and AFE makes one for Vette's. I just can't recall anyone posting their experience with any unit afterwards.

You should be able to fool the magride for a lot less than that. There's a company that makes a set of ballast resistors that replace the magride shocks so the module thinks the shocks are there when they're not. If you're electrically inclined you can buy the right value resistors from an online electronics supply house and just cut the connector off the end of the wiring harness pigtail and solder the resistors across the wires directly. The slightly more challenging problem could be convincing it that the ride height sensors are in place - the front's easy (just install them) but the rear's more challenging if the S550 rear LCA's don't have the mounting points for them.

@JAJ Please forward the company that makes the resistor. If anyone can tell me what the PN is for the resistors I can install them myself. The ride height sensors may be attached to the rear LCA?

Looking for advice and direction if anyone has insight.

The rear ride height sensors are the topic of this thread:
Last night at 2am I couldn't sleep so I went out to my garage and since I had my car on the lift I had a idea. I have a GT350 track pack and I also have a set of GT350R front and rear springs as some of you know. I've been so busy at work that I haven't had any time to work on my car but soon I will because the weather is gonna get nice soon and I want to enjoy it. Anyhow while laying in bed I had a though of doing this.
The R springs are supposed to lower the car 1/2". Some have stated it will or may change the mg perimeter. My idea is this. On the ride height / suspension travel sensors their is a link arm. My idea is to measure this angle as stock with the stock springs and stock wheels and ride height. Then note that angle, then after the R springs and my 305/30 FORGELINE-Michelin psc2 adjust back to that same stock noted angle. This could be done in 4 ways.
1) make a new lower control arm bracket that lowers the links attachment point for the sensor and restores the angle. Pain
2) make a new upper bracket that restores the sensors stock angle. Pain
3) slot the two holes on the bracket that holds the sensor, this can give adjustment to rotate the link arm to restore the angle.
4) and in my opinion the easiest, an adjustable link rod. It's just a ball stud on each end that can be bought and use some stainless steel all thread. These sensors pretty much do the same as the old air ride height sensors.3540256c75bd0252f76f468d17aa3812.jpg67d55f7ad9c52e63bbc5581065895612.jpg8785ee4f46d06f27cfcd230643e569f7.jpg3d8d73c8aa8e3429efcd07d3ded5e1b2.jpg

Restore this angle after lowering car.

Now for part 2 - which wiring harness do you have? Does it have the magride connectors for the shocks, the ride height sensor plugs and the 47-pin monster connector for the magride controller? It'll be easier to answer your question if I know what you're working with.

I have the GT350 harness. It has all the MR connectors.

Okay great! So, if the brackets are there, then you can just use the OEM GT350 ride height sensors. They won't do anything, but they'll at least enable the controller to work without an error code.

As for the resistors, the plug-in units from xineering should work. There's a cheaper solution - the actual resistors that fake the shocks when the shocks aren't there are available from electronics parts distributors for about $10 each (you need 4). If this track car will never have plug-in magride shocks, and if you know how to solder wires, or you know someone who does (a car stereo installer comes to mind) then they would be a very reliable and effective solution.

The parts I'd use are: https://www.mouser.com/ProductDetai...GAEpiMZZMtbXrIkmrvidB8tHLcYn%2bvCR/nT/Rjl5DY=

They're ruggedized panel mount resistors 1.5 ohms 10 watts that you can mount out of the way in the wheel well. Separate the pair of wires in the harness that normally go to the magride connector on the shock, cut the connector off and solder the loose ends to the terminals on the ends of the resistor. Then heat shrink the exposed wires and use a ring-type zip tie to strap the harness to the chassis so it can't vibrate.

@JAJ I purchased the 4 resistors from Mouser. THANKS for the info. I did have to replace the ride height compatible GT350 rear LCA with standard LCA so it would work with my coilovers. I'll have to find a way to attach the rear ride height sensors to the standard S550 LCA.

This is terrific information!

Good news: The standard S550 rear LCA’s do have the ride height mounting holes. Keeping the RH sensors should eliminate the code.

Bad news: the holes are not threaded. Will need to tap the holes.

Bringing this back up. Super helpful, thank you.

Do you know what the appropriate resistor would be for the ride height sensors?

Edit: Looks like the ride height sensors are fed a 5v ref signal. I'm gonna guess static ride height is around 2.5v (found this on a Camaro forum) so a voltage divider circuit would get me to 2.5v. If you've got any idea if I'm on the right track it would be much appreciated.
