S550 Race Weight

[BFish90g]

Hello everyone, new to the forums and my second post. I originally posted in the general forums, but didn't get anything so figured prob better here. Also thank you in advance!

I am building a 2015 S550 for the NMRA Limited Street class and crossover to Import Vs. Domestic/World Cup True Street class. The car will be a max effort 25.4/25.5 caged build. The current record in Limited Street is 8.71 @ 156 and 8.10 @ 167 in True Street. The car is Pro Charged and will be switching head units for each class combo. My main question is regarding weights. I will have to weight 3600lbs with a P1X in Limited Street and can drop 400lbs down to 3200lbs in True Street and increase blower speed 10%. Is it feasible to easily get these cars down to 3050lbs without driver and without majorly cutting up the car. What are weights with the usual mods:

-Drag wheels
-Drag brakes
-No airbags
-No AC
-No heater core
-Race seats
-No interior rear of front seats
-No bumper supports
-Tubular K member
-Tubular control arms
-Manual steering rack
-Tubular core support
-Fiberglass or carbon hood
-????

I am assuming the 25.5 cage, window net, parachute and fire system will add 150lbs.

That thread will help on quite a few of the things. That would be extremely light if you managed it

Can you drive without doors, trunk, hood and fenders? That might help. I really don't know if this car can get to 3000 lbs without slicing it up. That's a lot of weight to remove.

3,050 will be no easy task. Assuming your car is a base model it prob started somewhere around 3,700-3,900 with the blower system(without driver). I tried some of the typical gutting stuff and was able to get like 350 lbs out pretty easy. panel and glass replacement stuffs will get another 1-2 hundred maybe depending on how far you go. leaving you still well over 3,050. No A/C and removing the heater box would be huge, as well as tubular k-member. plus adding back 150 for safety stuff. Stereo system depending on model could add up to quite a bit.

Doable but it's gonna be totally gutted race car.

My car is really close to a full build now, the heater/ AC removed, no wipers, crash bars in the doors removed, manual rack, lightened front subframe. no exhaust, Baer brakes, Race Wheels / Tires, C/F driveshaft, and a full cro moly cage, that was 85 lbs. I kept a lot of the stuff in the car, could have got another 50 lbs out but I like that my car is really nice and still has most of the OEM amenities. In addition my car is a Performance Pack Premium, and is a 2.3 Ecoboost ( Yes im an odd one that likes the challenge ) The car right now is about 3300 to 3350 lbs with no driver, If you can figure out the weight between the 4 cyl and the coyote it will give you a good idea on what you can get one of these down to with lightweight parts and not hack the crap out of the car.I hate to tell you these cars are just heavy beasts !!! Below is a link to my build if your interested, my goal in 2020 is to get into the 8s at 150 with the car, been 9.60s at 143 at 3600 lbs . Good Luck with your build.

Hello guys I have a procharged v6 mustang I removed the whole back seeat, spare tire, jack, and, mats. The car weighed 3540 without me. I think I can still remove other stuff like the front passenger seat but yeah the s550 is heavy.
