Default Lowering Bolts vs LG Lowering Spindles

Just had the LG lowering spindles put on. Better ride, no noises, I should have done this long ago. The WCC bolts are Crap! These are them after 4K miles.




WCC bolt Top, Stock Bottom.



Stock on Left, LG on Right

Did you do the install or pay to have them all swapped? Difficultly and/or install price?

I hate how high the Z07 sits but I really don't want to screw with the ride height because I track the car, and stock bolts make very minimal difference anyway.

I am debating if I want to go the LG spindle route but am up in the air at the moment.

I have a Z07 as well. I went with the aftermarket bolts because of the rear lowering issue; mistake. The spindles are the way to go. Now it's sits just like before but the handling is vastly improved because it allows the natural course suspension travel. And no more noises.

Pretty common for those bolts to do that.....junk.

Since LG is local for me, I think I will go with their spindles!

Looks like nothing has changed with the WCC bolts. Zip claims that theirs are better, but you cannot go wrong with the drop spindles. They are, however, QUITE pricey.

I have been reading that ALL aftermarket bolts are suspect. They still limit the level of suspension travel. LG seems to be the most legit. Pricey yes, but after all, our cars are in the 6 figures.

Nope, ours are made in the USA and a different design. First our bushing is made by Energy suspension for us and it is the same ploy durometer as the control arm bushing. It is also Convex on the bottom so that it does not get pinched during movement of the lower control arm.
The LG spindle is a better way all together but price prohibitive for allot.

If you want the car lower to look good at car shows then lowering bolts aren't too bad, but they won't last long and you're compromising how well the suspension works.

If you intend to drive the car even half aggressively or track it then the spindles are the only way to go.

Exactly. I just could not take the noises anymore. I do not track my car but I do lots of Spirited driving and the "clunking" really bugs me. Now I have no more noises and the suspension feels more planted like it should have been from the factory. I hope on the next-generation Corvette they limit the wheel gap between the fender and the top of the tire. Corvettes are no longer just for old dudes that have trouble getting in and out of the car. :-)

A pet peeve of mine...
American car manufacturers keep companies like Eibach, etc. in business with the ridiculously excessive fender-well clearance.
Geez, come on...we can do better!
Of course, if they did it right then we would have one less thing to complain about...so there's that.

Seriously, why do the Germans usually get this right and Detroit never seems to?

Any before and after pics. Also I assume you had to realign the car? Same specs or were they different?

I know these lowering bolts lower the car slightly. Do you still need to do an alignment?

German design the car around the wheels, while Americans design the car then throw wheels on it as an after though of design.

These are absolutely the only way to lower the Z06/Z07 properly to maintain the correct suspension geometry and keep
the car handling safely. These lower the car exactly 1-inch if no other adjustments are made to the suspension. The car
should be checked for alignment afterwards! The Z07 in particular has the exact correct looking stance afterwards.

I traveled down to Lewisville, TX the last week of June to have LGM install these on my Z07 and I believe it to be perhaps
the best mod for both performance-handling and aesthetics that one can do.

One should not lower the car by adjusting the lowering-bolts and especially by installing bolts that will allow more travel
than the factory bolts!!! It reduces spring-tension, altering the way they will work and reduces the amount of shock travel
allowing both the bottoming out of the shocks and the car!!!

Is there a problem with suspension bottoming out, etc. using the stock bolts only?

BTW, is that your lowered car in your avatar?
If so, can you blow up the pic?

How exactly does lowing the car using the OEM bolts adversely affect handling?

I have a Z51 which is lowered using the OEM bolts. I track it often & want the suspension working optimally, since I am trying to become a better, faster driver.

Thanks.

The key is the suspension travel. The Z07's will not lower as much as the Level 1 & 2's so you either need to go with aftermarket bolts, or do it right and go with the lowering spindles.

Check out this video. It may answer your question better.
