Yup. And thus begins the transition from "just having fun" to "taking it seriously".

I don't know how much power or how good of a hook the rear can take before she blows on this car. But I DO know what the 4th gen's were like, and I remember that even a good hook w/ 400+ RWHP could cause an explosion.

P.S. Might consider that: But Milan is closed this year, and no announcement yet on rather it is re-opening. (New ownership I guess?)

I may have to try US 131. It won’t be on July 8th though. I’ll be at CF.

Milan is open this weekend.

You can't lock the suspension on non 1LE's 2020+ MRC is an option, not a standard. 1LE's come standard with it, Non 1LE's do not. They don't have MRC, just standard rigid suspension. Which I guess is what you said lol. I need to learn to read better.

The only option I can manage is steering wheel tightness. I guess choice of wording is bad on my part. My car is a Non 1LE Non MRC

Your car is a ZL1, which has heavy duty driveshaft and axles from the factory. You should be fine IMO, as I have only seen a single post from a modded-ZL1 owner breaking an axle on DRs at the dragstrip. With all of the 9-second and 10-second ZL1s, that is a pretty low failure rate.

The OP having an automatic SS with bolt ons is also likely fine with DRs at his mod level IMO. I have run in the 10s on DRs with the stock SS driveline in an auto car, and plenty of others have as well. Once in a while, someone has broken a driveshaft in an auto SS, but only a few have reported that with just bolt-on mods. With the brutal torque hit of a PD blower, breakage of the stock SS driveline would then be more likely IMO.

To make your passes down the 1/4 mile as easy and as disaster free as possible, put a good drag radial on the car and there is absolutely no better bang for the buck. Spinning at any time can get a experienced person in trouble...beware.

the 10 bolts in 4g cars were a lot like women. they all seemed like a good idea but you never really knew until you had some time on her.

i broke 2 of them, from a roll, in a near stock power level m6 car that went to the drag strip 5x? and never even had drag radials on it. before that i had an auto car that saw at least 300 passes and lord knows how many street pulls, burnouts and general shenanigans. at least 100 of those passes were 1.7 60' or quicker. that car lived on mt et street DRs.

i think i recall seeing something about brandon hills car going 9s @ 130+ on the factory stock rear & axles for like 2 years before it had any issues.

the op will want a decent drag radial because it will be very evident during the first night out that a 20" street tire leaves a lot to be desired on a drag strip.

My 97WS6 auto lost a rear-end with just bolt ons.
The 98Z28 in my driveway has a 12 bolt Moser.

Update: Since Milan seems to be open July 9th Test n Tune 12pm to 6pm

I will be going there instead of US-131. Weather doesn't look to promising July 8th anyways and US-131 is 150 mile drive.

New spark plugs NGK Iridium IX
Having the (I believe it is the Trans filter changed)

Also having the intake cleaned as well (no catch can yet)

Is there anything else pressing I should also consider?

Tires?

Tires have less than 4000 miles on them. So lots of tread left. I don't do burnouts so nothing lost nothing wasted... YET lol
