People have posted some DIY methods. I think removing the shock actuators and setting the rears to max firm and the fronts to max soft. And something about disconnecting one of the anti-roll bars.

Re: Who does suspension upgades ? drag racing?/
The ZF.DOC does some nice beam plates. I have these installed and they work well. Tell him I sent you! Goldcylon
C4 Beam Plates (Fits all 1984 -1996 Corvette Drivelines) Lifetime Warranted Retail price - $189.00 To Purchase call (602) 319-6575 or email www.billb@zfdoc.com These multi-purpose driveline support reinforcement plates can be used on all 1984 through 1996 model year (C4 or 4th Generation) Corvettes. We have found that most C4 Corvettes inherently experience a slight amount of twisting at the fastening points of the support beam to the transmission and differential housing connection surfaces. Although fastened with high grade bolts, self-locking nuts and adhered with factory sealant, the driveline components of the C4 Corvette still experience some level of counterforce load-induced lateral deflection between the members while under heavy loading. This allowance of flex in the driveline beam fastening joints creates a condition where the chassis structure must additionally contend with. One common side effect of this phenomenon is where the rear of the vehicle tends to kick out to the right during aggressive high RPM gear shifting. Notice that the C5 or 1997 and newer Corvette was redesigned so that lateral deflection of the driveline is practically non existent. The C5 Corvette driveline consists of a drive shaft within a tube that has a bell housing <SPAN style="FONT-SIZE: 10pt; mso-bidi-font-size: 12.0pt">fused to each end.

You didn't say what tires you were running, or what suspension setting you use.
You also didn't give a clue as to your launch technique. What RPM are you launching at? Dumping the clutch, or feathering out off the line. The more you tell us, the more we can help.

Re: Who does suspension upgades ? drag racing?/
sorry for the incomplete info. also 60 ft should be 2.02 not 292. I am using mt et streets @16lbs have done the best withsusp on easiet shock setting . 1/2 tank of fuel spare tire removed . do the best burnout i can without a line lock. then leave at betwween 2500 -3000 ,with a fast release of the clutch ans squeeze the throttle. short shift 1-2 @6500 2-3 @ 6800 as wellas 3-4 go through the lights @7000=if i carry first to 6800 i spin the tires way too much .. if i couldget rid of the squat i think that would help . also thinking of trying a 16in tire maybe more sidewall would help

Re: Who does suspension upgades ? drag racing?/
If you run too little pressure your tires will cup and youll lose your contact patch.
You can lose on the big end also with too little psi not to mention it can handle a little funny at speed. Try Fastlane or Dick Guldstrand, too.

Jeb Burnett on corvetteforum (jburnett) is a great source for IRS upgrades.
