My understanding is that Koni’s are made for the stock Corvette spring rates.

Will the Koni 3013 work with VB&P Extreme Springs K=1350 front/K=850 rear?

Yes they will work. They have plenty of rebound adjustment. The shock body is to long, but that's another story.

What class are you trying to compete in?
Why do you think you need that much spring rate and excessive - camber?


Get the delrin bushings,wheels and tires first. If you are against going coil overs get a T1 front spring and a stock Z06 rear spring. The konis will work great with them.

Nokones

Koni are great shocks. Since you have gone to the Vette Brakes & Products extreme spring rates, you may need to have the shocks revalved to compliment the stiffer spring rates. I would contact Sam Strano for advice.

A clue would be if you are adjusting the shocks, either direction, and the handling gets better and you run out of adjustment.

Another source for revalving Konis use to be Pro Parts and/or Guy Ankeny.

I compete in CAMS. Moving to SSP or SSM with Hoosier A7’s and drop spindles will be fine with me. I AutoX just for fun.

To help with hard braking nose dive. When I was researching GM T1, Hyperco and VB&P springs I found a less than year old pair of VB&P Extreme for the right price and thought I’ll try them out. I’m for all the negative camber you can get and then set the rear camber at 1.0 - 1.3 less than the front.

I’m not against going coil overs, I've not done any research and still like the option of putting on 285 tires and running STU.

I don’t want to revalve my Koni’s. I’d rather get DA like MCS 2-way.

I've seen a couple of the vb&p front springs delaminate and cause the car to start to sag. Just pay close attention to them. I'm not sure what their warranty is on buying second hand. That's the primary reason I went with the hyperco leafs. Track front/ street rear. Haven't had a problem with them for two years now. The other Corvette has gone through 3 front springs and is now on coilovers.

Go find Lane Borg's STU build post and read that. He has a lot of good information about spring rates, his delrin bushing kit and what works well.

Here a link to the STU thread mentioned above.

Mine did. Had to overnight another one from Fl. to event in Bowling Green - $500 spring, $250 overnight. Got home to the shop and found out some of the new ones are delaminating, also. I am going to go strictly coil overs when this one craps out as some friends have done.

How is your ride height with the track front? Were you able to get it to stock or slightly less than stock ride height?

Looks like it. I couldn't get it as low as I could on stock springs but it's definitely lower than stock.
