I bought some used ones from a member on here to help me at the track with my mt et streets from walking so much higher in speed but my question is on the 15X4 he told me that i dont have to do any mods like spacers or anything he said they will just bolt right up. Just wanting to make sure i dont need to buy anything . Keep in mind these will only go on track day which is prob twice a month . They also have some kuhmo tires on them and i have et streets on the rear how will they mesh(the rears are on stock firebird rims i think 26x11.5x16)? I imagine better thant my 17s i ran last time and it walked all over the place. Thanks for any help

i had convo pro's on the front of mine without any mods. Be sure to use the proper shank lugs and washers though.

I don't recall the proper shank length. Maybe someone else can chime in.

You will have to grind some with the 15x4 if they are 2 5/16 backspace. The 15x3 1/2
bolt right on but stick out more . Not nearly as much grinding as with weld wheels.

No problems with the convo pro's.
I'm running 15x8.5 and 15x4 on my '98. No grinding needed at all.
Call Summit and a tech can put you on the right lugs over the phone.

Shank length is .490 for cenerline convopro's .If your 15x4 have the 1.75 backspace you
don't need to grind, they just stick out 9/16" farther out each side.

Im guessing there 3 1/2s since the guy said they bolt right up with no spacers or grinding. I need to find some lugs

I need some new tires for my 15x4 convos. Does anyone have any that will fit it and that will mesh(non radial) with my mt et streets? i would like some mt et street front runners if possible. If not im gonna have to buy new next week.

Get M/T Sportsman fronts. If the car is heavier, go with the 8-plys and they won't bulge as bad.
