You shouldn't use a 28" tire unless you're running out of gear in 4th because it will slow you down. 26" tires are good for 110-112mph @ 6,000 rpms. The reason your car ran a 99 miles per hour is because of the 28" tire and because it hooked. Before you were probably (definitely) spinning and that's why your miles per hour was so high. 105-106 miles per hour is the norm for full bolt ons and 4.10's at around a 13.0 . A 26" tire will get you into the 1.7x 60'. The steeda sport springs aren't the problem. People have cut 1.6's and 1.7's on them. For the strip they are much better than Eibachs or H&R's because they have weight transfer similar to stock.
