Default What size weld prostars for my 94?

Im going to buy some weld prostars,but I don't know what size I should get in the front or the back.I have the baer big brake kit(13 inch rotors) up front and I have stock rotors/brakes in the back.

what size would eliminate or minimize grinding??

im also dropped on eibach prokit and plan on running the biggest slick I can without mini-tubbing

You won't be able to fit a 15 inch Pro Star on the front with that brake kit.

I run Pro Star XPs 15x6 up front and 15x10 rear. Stock LT1 brakes which work fine for me.

I agree, dont think you will fit that brake in a 15" wheel.

with the big brake kit on the front, and the drop....your plans are going the wrong way for a drag wheel setup. You will probably have to find a 17" Pro-Star XP, which aren't made anymore I don't believe, so it would have to be used, and may still have to grind. any 15" Pro-Star is not going to fit the front of your car.

As far as running a big slick with a lowered car, you might be able to get away with a 28x10.5 ET Drag.

They make 17" front runner wheels but they are $$$$$$$$$$. I would probably just get a set of slicks mounted on a spare set of wheels and not worry about the fronts. That's what I do cuz I have the same Baer brakes on my Z. I am going to probably go with the Baer system that maintains the small rotor on the turbo car and run Prostars.

I plan on running 15x8 Prostars with 275/50R15 MT ET STREETS. That's a 26" Tire..that's an ideal setup with a 3600 Stall and 3.73's in the back.

thats the correct rim for the rear. i am running those with a 28/12.5 ET street. i had to grind on my caliper some and the bump stop. for the fronts you might want to run a rim thats able to support the weight of your car. if you plan on crusing the streets with them. i run these up front WLD-96-55276 with MTT-1573 SPORTS FRNT 26X7.50-15LT 8 PLY . i played it safe on my choices. you will also need a spacer for the front , i used this one MRG-2371 WHEEL SPACER 5/16IN. good luck with your car

they are just shorter (100-7708) with the 100-7713 my stud comes to the very end of the lug nut. of course i am running a open lug so i don't have to remove it for tech (if they actually ever decide to check it, our track is laid back)in my eyes the 100-7708 wouldn't be long enough to be nhra/irha approved with the thread engaugement rules (thank you injuneer, for setting me straight on that issue) lung info "Part # 601-1422
X-TRA LONG MAG SHANK 1.380" Shank Length X .687 Diameter 12MM x 1.5 RH Open End Nuts with Centered Washers" the rules reads like this, the thread of the stud must be in the hex part of the lug, atleast the same amount as to match the thickness of the stud itself. so if it is a 12mm stud x what ever length. the stud must be 12mm into the hex head portion of the lug. thats the way i was told the rules stated it, if i'm worng i have a little more over kill on saftey then.
