Where I have to turn the screw to lower the suspension, left or right ..?



Thanks

 

Well....I'd label the directions differently, but...

You need to turn the bolt in the direction you have labelled "right" - i.e., counterclockwise - to lower the car.

The bolt screws in from below the leafspring, and to lower the car you want to reduce the distance between the head of the bolt (the rubber bushing that rests on the lower a-arm) and the leafspring.

In order to do that you need to screw it so that there are less threads below the leafspring and more threads above the leafspring.

So.....turn in the direction you labelled "right" to lower the car.

+1 on everything BEZ06 said!

 

sorry, I do not understand ..

 

the black pad at the bottom arrow, needs to be closer to the leaf spring at the top of the arrow. U want to see "less" threads then you see right now

 

Exactly, but another simple explanation just in case......

You want to adjust/screw it to where there are "more" threads on TOP of the leafspring vs underneath. This would require turning the bolt head counter-clockwise. What you have pictured above is a higher ride height where as if there were "less" rusty threads in the above picture it would make the ride height lower.

 

This is correct again, but going back to your first question if you turn counter clockwise (like loosening a bolt), it will lower the car (the direction you have labeled "right"). That will get you where you want to go.

Be sure to get an alignment after you are done! You don't want to ruin any tires with your new, lowered Corvette!

 

semi-hijack ... when you lower the car, does it change the camber neg or pos???


also to the OP = lube those bolts real good with WD 40 or similar before turning.

 

Ok, ok, I understand.

Thank you very much to the forums , Thanks.

 

I'm getting ready to install new wheels and lowering. How much drop will I achieve with turning the stock bolts? What's the difference between stock and aftermarket lowering bolts?

 

All the aftermarket bolt except the HardBar ones were junk, but they do lower the car more than stock bolts. I finally gave up and put Pfadt Coilovers on and solved all my problem with aftermarket bolts.

 

The Corvette has a pretty aggressive negative camber curve. Typically the lower you set the static ride height, or the more the wheel moves up in bump travel, the more negative camber the wheel will see.

The lower you set the car with the factory leaf springs the more suspension travel you effectively eliminate. The more travel you eliminate the more likely you are to be running your car frequently on the bump stops which can produce rough ride quality and unpredictable handling. Depending on what point you started from you could potentially see an inch or so of lowering, but we don't suggest users of our replacement shock products go lower than 1/2 - 3/4 of an inch below stock... generally anywhere within the factory bolt adjustment range is ok, but typically higher is better. You can have the greatest shocks in the world installed, but with very limited shock travel while lowered on lowering bolts you're not going to be getting the very best ride quality or handling from your Corvette.

A little lower on the factory lowering bolts is good. A lot of lowering with the factory leaf springs can be bad.

That's one of the big reasons we developed our coilover products. To give Corvette owners a way to lower their cars without the side effects of doing it with lowering bolts.
