Hello all, pretty new to the forum and am enjoying all the info. I am currently rebuilding an 88 monte ss and am wondering about suspension packages. This car will be an ls swapped cruiser. I would like a lower stance but I’m just as concerned with ride as handling. Our roads in Saskatchewan Canada are full of frost heaves and pot holes so going to low or too stiff would be bad news. Anyways I’m interested in this package but wonder about any real world experience or advise

It’s the stage two kit with control arms etc.
I am keeping stock diff and would also be fine with changing all bushings in factory front end and adding some lowering springs etc but this kit seemed well priced. Thanks all.

Bilsteins are a great shock I run on all of my g-bodies, at least any that are spring/shock setups, the BMR rear 1.5" drop springs are in my SS now, I like the stance and the progressive rate similar to Eibach's. There are a ton of suspension options out there, not saying to avoid BMR, they've been around and make good parts. UMI is a very popular one with g-bodies, others like Global West, Ridetech, Detroit Speed could be worth investigating. I would agree not dropping it drastically if your roads aren't great, same issue here and for many people although it also depends a lot on the wheel size/tires you run for that too.

That kit looks good, and as PB86SS/87LS pointed out, there are a few equivalent kits out there.

Just one caveat, however: I would vote strongly against using their rear control arms. They tend to bind with any significant suspension motion. Despite all the negative things they say about the stock arms, they actually work better than the arms they sell. I've written extensively about the pros and cons of the GM rear suspension design in our cars in case you're interested in diving into details. This thread is the most comprehensive: http://www.montecarloss.com/community/ubbthreads.php?ubb=showflat&Number=1068445#Post1068445

Thanks for your reply’s. do you find the rear Bmr 1.5” drops to be stiff? Happen to know the lb rating on them?

I don't recall...I might of caught wind of the lb rating, but with all of the other lb ratings I might be mistaken in what it is. I'm sure BMR would be able to provide that info if you asked. I don't think they are too stiff. If you are going from stock/stock height you might notice it a bit stiffer, but that is one side affect of suspension that generally handles well/lowering, the ride will be a bit more stiff. Lots of factors at play but don't think the 1.5" drop, with good shocks, will be too stiff at all.
