Hi, my IRS in my 99 cobra is stock besides 4:10 gears other then a IRS brace what else is best to replace to stiffen it up. I dont have the cash to replace the halfshafts now. I would love to take it to the track and not snap one. I wont be dumpin the cluch just easin out of first with street tires. Any help would be nice and where i can find the parts.
