I think it was the Ridetech guy who said the main advantage to coil overs was adjustability. Its easier to change ride height and spring rates with coil over.
BTW...my 9 leaf spring must weight a lot.

50 lbs for a steel rear transverse spring versus 7-8 lbs for a composite transverse spring. The composite will give you the best bang for the buck, by far, for weight savings, ride comfort, and increased performance! Other systems might be slightly better but the incremental dollars spent is MUCH higher.

Goals are just to improve handling. Won't be on racetrack again, except nostalgia drags, auto crossed in the 80's. Current suspension is basically F-41 gymktata setup. 350 lbs springs in front, koni gas shocks all around. 1" sway bars front and rear. 7 leaf GM big block leaf spring in back. Car has aluminum 509 Dart motor, w/original small block 327 in my storage shed. Current suspension has not been upgraded in 30 + years. Also have 17" wheels and Falken ZR-255 17 rear and ZR-245 17 front with offset trailing arms.
Duntov also says changing the rear 7 leaf steel spring for fiberglass mono is the LAST place a Corvette needs to shed weight, right over the rear axle steel spring provides needed ballast.
Leaning toward just upgrading suspension with new stuff from Duntov Corvette. Again, they say no performance advantage with Ride-Tech or Shark Bite coil over setup or Vette Brakes mono spring setup although Vette Brake system cuts a lot of weight front and back.
Not concerned about "bling" more into actual applied results.

Polyurethane bushing all around.

Its a typical case of an outfit who thinks theirs is the only goods or service worth a ****,
When i hear a company bash the competition no matter how big an ego they have i write them off as a walking pile of fertilizer,
Sad part is when an outfit with poor customer service uses the name of a legendary and respected person of that field.

I'm not sure what you consider "Race" calipers. Pretty sure there are guys on here actually racing with stock calipers without issue. If you don't want stock what is wrong with the Wilwood? Or Baer? Real brake companies. Supporting vendors carry them with Forum discounts.

But as for braking ability since all the calipers use the same brake pad, they all brake equally as well using the same brake pad material. Only difference you will see is selecting a different pad material.

For the street I think the best improvement in breaking is to replace the decades old design tires to newer performance tires, 17's, 18's, 19's. The old 15's will slide long before you reach the end of the stopping force the stock breaks can accomplish. I have hydroboost with stock calipers with, o-ring seals and good pads, not racing pads, and you can near throw yourself out the windshield with my 265/285 max performance tires. Track is a different matter most people will never deal with.
As for the original question, no matter what type of spring and shock you use, you need to match the suspension to your use intentions. On the track, assuming equal drivers, the car that will go around the track fastest is the car that has the entire chassis setup dialed in best, be that transverse spring or coil over. On the street, I don't think coil overs are going to be any kind of advantage except the bling factor.
