Tested out New Suspension
Merry Christmas C5 folks,
This past summer I had suspension upgrades installed, fast forward and I took the C5 our for spirited driving to ge the feel for it. The car is dialed in.
Here's the suspension/chassis parts:LG Motorsports Billet drop spindles, G Speed spec Penske Coil Overs, Spec Corvette T1 Sway bars, with poly bushings, progress end links, Borg Motorsports Premium 100AF bushing, AMT Camber lockout kit, SKF hubs, TPS motorsports1/4” belly pan.
I think this is it for now, but next up are a proper FIA seat, harness bar, and some track wheels and tires. The car currently weighs 3,130 with the Braille lithium-ion battery. I think the seats (Sparco QRT Circuits 15 pounds each) and Apex wheels (18x11 & 18x12) 21 pounds each will take approximately another 50-60 pounds out the car putting me around 3,070 pounds.

I bought all suspension components from pervious owner who had it for the car before I bought it.
The tunnel plate is a TPS Motorsports piece with thermal shielding. https://www.tpsmotorsports.com/test2...shielding.html

Ohhhh the tunnel plate. I thought maybe you found a belly pan for aero to cover the under engine areas out to the suspension. I was surprised to hear that slightly more skilled manufacturing piece associated with TPS, but the tunnel plate makes sense. They're valid kit and do firm up the chassis.

Mono-ball at the bottom replaces a ball joint so be ready for a rougher ride. There are more pros than cons though.

It's approximately twice the thickness as OEM and dials out torsional loads. I'm not sure I notice it much. It's been on there for awhile now and I might have noticed a little initially but can't tell the difference now.
I guess you could measure performance data on a skid pad and lao time testing with OEM vs Aftermarket plate.
I think 9 lives racing makes front under carriage panels/parts for the C5.

How harsh are the mono *****? My car intended to remain primarily a street car I went with the Borg delrin 100af bushings and am keeping factory camber bolts vs AMT. The rest is progress bars, white line links, and my old rebuilt RideTech HQs.

I had everything installed at once so I can't say which component contributes to most harshness, but I don't think it's the Delrin bushings. I think it's the bottom side of the drop spindle with the mono-ball.

I hear you and luckily I didn't pay retail. LG did have a sale around Black Friday and they were like 2,600 I believe, but they are back to normal prices I just checked.

It does have Borg Delrin 100AF bushings but I don't think that contributes to NVH like the billet spindles with monoball bushing.
