1969 SS BB need some advise

No matter what im taking these rims and tires off this car and getting something else. So help me out, i hope to go order them tommorow.


As it sits, 235/60/15 mounted on american racing what look like toro thrust d rims. Not sure if they are 15x7 or 15x8. but i know this much they rub with passengers in the car (fronts basically). Im going to beef up this suspension (NOT LOWER IT THATS FOR SURE).


So talk to me, 15x7? 15x8? looking at american racing rims, ar-23, maybe outlaw 1's.

As far as tires, should i stagger them? 225/60 up front 255/60 out back? something like that? or stick with 235's up front on a 15x7 and hope they dont rub again? Like i said i have no idea what size rims these are other than 15's.

Re: 1969 SS BB need some advise

FWIW, I ran P245/60/R14 on 14x6 with a BB back in the day on my first 1969, no rubbing issues. On the 1969 mouse powered car I own now it's 15x7 Rally's all the way around w/ P235/60/R15, no rubbing issues even with passengers in the vehicle.

You may want to double check the Torq Thrusts...I have seen 15x6, 15x7 and 15x8.5 in that size. I know someone who runs a 454 in a 1969 with 15x8 Rally's and P225/70/R15 up front and surprisingly it doesn't rub...all brand new stock suspension.

As far as the tire sizes, it depends what you want to do and what your goals for the car are in regards to straight line performance, cornering/handling/braking/ etc....Back in the day even in the late 1980's & early 1990's many first gen Camaro's were driven daily by 18-24 year old kids who bought these cars as their first vehicle. They were driven in rain and once in a blue moon even snow too....Yea prices were much lower then for a decent daily driver.

A good combo would be 15x7 in the front w/ P235/60/R15...Some guys ran P225/60/R15 Goodyear Eagle VRS tires back in the day which was the road racing tire/oval track tire in a V speed rating ran by the 5.0L Mustang GT & LX's during the late 1980's/early 1990's...Those Eagle VRS tires worked great on Camaro's.....In the back you could run a 15x8 w/ a P255/60R15....The specs on most torq thrust's are 5 x4.75 bolt pattern w/ 3.75 back spacing in a 15x7....The Tire Rack recommends P225/60/R15 on the front for a 1969 w/ that Torq Thrust 15x7 application.

If it's any re-assurance I mounted, balanced, sold, repaired, warranty adjusted, installed, fitted and managed tire & auto stores/service departments when I was younger. All these places are still in business today because they did business the old fashioned way with respect for customers, integrity and honesty!

P.S. I know what the AR23 looks like too....Nice old school choice! So in short if you want a different look P225/60/R15 in the front w/ a 15x7 and a 15x8 w/ a P255/60/R15 in the back...I just got my camaro back after 2 years and hopefully I can start playing with it sooner rather than later. I hope this info helps you out...Happy Motoring and Be Safe!!

Re: 1969 SS BB need some advise

Well i got 15x7 fronts 15x8 backs. Cooper cobra 235/60/15 in the front and 255/60/15 in the back. Mounted on AR23's. Looks awesome. I have 4 leaf muti's in the back. If i hit a big bump i get a little rub. But for the most part everything is fine. Will fiber mono leafs help that situation at all? I have 4 leaf multi's in there now. They are pretty much new. (the previous owner replaced everything)

Re: 1969 SS BB need some advise

FWIW, I had mono leafs on my first Camaro....after I replaced the mouse, glide & 10 bolt rear with better drive train goodies I ended up going with HD 5 leafs in the rear, HD big block springs up front and much stiffer higher end shocks all the way around....I was running L60x14's on that car which equates to P265/60/14.....A buddy of mine was running N-50x15 in a very nasty 454 BBC powered 1968 Firebird back in the day...If memory serves me correctly N50X15 would equate to 315/50/15 and his car had HD 5 leafs with HD shocks and never bottomed out even when he stood on it in the middle of nowhere.

4 leafs were commonly found on Z28's....My 1969 Camaro is not a Z28, but it has 4 leafs....it bottoms out sometimes over the ever so straight (LOL) Chicagoland pothole roads.....I don't know how old the leaf springs are but they don't appear to be original...

COPO's, Yenko's, ZL1's, and very high end big blocks to the best of my knowledge were equipped with mostly with Heavy Duty 5 spring multi-leafs which I think was known as the F41 suspension although some F41 cars had 4 leaf springs. http://www.camaros.org/suspen.shtml#MonoVsMultiSprings

I can't promise you HD 5 leafs will solve the issue but based on my experience and the experiences of my friends & co-workers over the past 15-20 years, HD 5 leafs generally solved the issue of bottoming out. The concern may be that HD 5 leafs would not handle as well around turns due to their raised height and increased stiffness vs regular standard duty 5 leafs or 4 leafs.


I hope this info helps you out.

Re: 1969 SS BB need some advise

It certainly does, thank you. What would be a good source for buying 5 leaf hd springs? Any install tips? Any special shackle kit i should use or anything?


Appreciate your help

Re: 1969 SS BB need some advise

I have 15 X 8 Vette rallly wheels on my 69 all around. 245/60 in back and 235/60 in the front. New springs were put in when I installed the wheels 20 years ago! As time has gone by I get more positive comments on the wheels as everyone has gone to newer Thrust or whatever style wheels! Now the rallys are "different"! I have the 67 flat caps on. I moved the inner wheel well back with spacers about 1/4" or so and have no rubbing issues. Good luck!
