So, Iíve purchased the car, and my dad is picking it up for me in Ohio. It should arrive by Monday. I also purchased the Performana 25 wheels on eBay. They should arrive by Thursday. The lowering springs should arrive by then, as well. All in all, Iíve the car, the springs, and the wheels taken care of. Iíd like to have the car sorted quickly so I can enjoy her.
Do yíall have thoughts about the tires I should put on? Do I need spacers, and should I also buy shocks for the back?
Thank youóIíll follow up with pictures as things progress.
FYI...you are moving kinda fast by buying modification things before you fully assess the overall maintenance needs of the car. These are old cars and even the best usually dont arrive in perfect condition. That said? I pretty much did the so same as you re: buying wheels and springs quickly. LOL.
If you have SLS rear suspension, you will hope that the rear shocks (called rams) are in great shape. If they arent leaking, they will be fine. If they are leaking and need replacing, it's near impossible to find new ones. And if you do, price is going to be high. YOu can find used, and hope they arent leaking. But other option is to totally remove the SLS system altogether, and get non SLS type rear shocks and different springs I think. You'd then want to read various threads that discuss removing the rest of the SLS hydraulic system.
With the Performa wheels, the standard center caps wont fit as the cars grease caps on the ends of the wheel hubs will protrude too much. You'll need to obtain raised center caps (not attractive) if you want to not use spacers, or use the standard center caps and use 10mm spacers up front and not sure of the minimum size spacer you'll need for the rear. I like my wheels/tires rather flush with the fenderwheel edges so Im running 25mm spacers in the rear. Im running only a 3mm or 5mm (cant recall which) spacers up front, but I did have to dremel the backside of my stock center cap in order for them to fit without the greasecap hitting them/pushing them out. If you go for spacers, you'll want 5X112 bolt pattern with 66.56 or 66.6 center hub bore.
Again, all of this info is detailed in several threads, including the one I linked above to my car/my journey.
But in my opinion, your first priority needs to be tovisually inspect key areas for signs of any rust, and address accordingly. In the SEC's, lower corners of rear glass around and under the rubber trim are prime areas that if not caught early, can lead to major cost to address as it requires rear glass removal. Not easy, not cheap.
