An irs on these cars has always been a WTF IMO.
Id really be curious to see a comparison in handling with a car running the best setup SRA ( 335’s/ 3link/
Panhard bar/torque arm) versus a 275/285 tire width limited IRS.
ALL of the IMSA fox mustangs that ever were have an SRA.
ALL of the Drag radial class mustangs have an SRA.
This is another mod that serves no purpose other than being able to say you have it. Much in the same way going full out on an SRA when the grand plan is to have a daily drive-able street car. One one hand, maxing out a solid rear axle as described above will be a sonofabitch to live with on a bad stretch of road, on the other hand, going through the expense to properly build and install an irs just to drive it around in town has me scratching my head........Why?
Follow me here now.......because this is where “ the rubber meets the road” ( You like that segue?)
The guys that just have to say they have a 750-1000 hp combo that can’t, or never use it are the same guys. ( like 500 rwhp isn’t already pointless on a non traction controlled street tired car). It’d all be different though if it is a requirement for the intended usage of the car..( competitive drag car/flying mile)
That car lives it life in the garage, waiting on the weekend. Maybe one day it gets driven to work, or a local cruise night, but the majority of the time it’s spends its methanol/C16 swilling ass sitting waiting on a Friday or Saturday night. So,....the build purpose, and it’s intended usage jive...it’s a pain in the dick to drive on the street, but fast as sht when any of that matters. I’ve been there, and will never again have 40k worth of old assed car sitting, waiting on Saturday, when I can take it to a track to see if I can’t go and fck something up.
So.........95% race car, 5%street car.
There is so much more potential using an SRA when performance, and looks matter. Big, stupid width tires can fit inside the stock sheetmetal, and the skill required to minitub, or even do a full tub to make them fit only requires a fraction of the skill hacking the quarters require. That is so far beyond skill set for even an accomplished body man, and when you finally find the guy that can do it......Say goodbye to your wallet...cause dudes gonna take all of it.
The Monster has 315’s, if I wanted a 335/355, all that would’ve required was an extra inch added inboard to the strip of steel I welded between the gap I created in the stock wheel tub. My car is a street car. It was built to be. If I take it to the drag strip ( my 1% usage) I could throw on a set of drag radials, and the
suspension will work. It won’t be ideal, but it won’t wheel hop, and it certainly won’t spit a half shaft. Everything under the car was built for it, but with compromise. I don’t give a sht if it’s a couple of tenths slower than it coulda been by living with a stiffer rear spring, removing the sway bars, and setting the shocks struts to drag mode.
this car has always been the sht, in my opinion. Pure show car that gets driven to show events. Has something like a 345/20 under the rear quarter. The car was built to ride in the weeds, actually cut the axle tubes and welded them back with camber built in just so he could put it as low as it is w/o having the tires tilt inward when he drops it.
The normal to the story is build the car for the 90% of how it will be used, not for 10% of the time it’ll spend somewhere else.
ton of wet sanding.
