Anyone know where I could source a cobra IRS in the SC/GA/northern FL area that isn't gonna make me broke. I wanna swap it into my 93 coupe and yes I know it requires some fabrication.
I'll let Scott (90sickfox) give advice on the pinion flange install. I dropped my center section off to a local reputable driveline builder and he installed FRPP 3.73's and new clutches and seals for me along with the pinion flange swap.-Dope write-up makes me far more comfortable doing mine, and I think I might do the hole in the trunk method. I'm waiting on MM bushing and sleeve kit for the IRS not a big fan of taking things in and out a bunch of times. Any advice on the pinion flange swap? I'm grabbing a beam type inch pound tq wrench today. I am going to measure the drag before, pull the cobra flange, install the smaller diameter flange, and than tight until the drag matches the before measurement. Sound right?
-it is a 3.55 the junkyard verified and I verified once I got it.
I haven't had any wheel hop the past couple years up until a couple weeks ago. I put my kids in my car, it was a cold morning (about 36* ambient), and my summer only tires were hard as rocks. I pulled up to a stop sign and rolled through it because I saw a small opening in traffic so in first gear I gave it 1/4 throttle and just lit up the tires. The rear end shook violently and freaked my kids out. Last week I let the twin screw eat in second gear and roasted the tires when it was about 60*+ out and zero hop. My BFG G-force comp tires do not like the cold!Looks like ya know what you're doin'.
Just for folks that don't know....a drop of blue Loctite helps keep those axle bolts from loosening over time. Tried red Loctite....bad idea.
The IRS in my car is all stock except the addition of a girdle. This turbo car was the first time I ever experienced wheel hop. I think it was due to the alignment and a little more power.
Guess it's time for me to put together an upgrade list for myself.
I've installed a bunch of bump steer kits for IRS but never got around to doing my own. They do help the cars feel more stable....especially exiting turns on the throttle.
