5 Suspension Mods That Can Ruin Your Car. Camber Kit Product Link - http://amzn.to/1XKXqw2 Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 Lowering springs, lowering clamps, wheel spacers, camber kits, anti-roll bars, coilovers, the works. Suspensions very frequently modified but very challenging to setup in a performance enhancing manor. Lowering clamps lower your car without changing the spring rate, lowering springs won't match the damping rate of your shocks, camber should only be slightly negative, wheel spacers can decrease braking stability, and roll bars should be used to fine tune steering dynamics.

I'm pretty sure the spring clamps are for installing springs that are longer than the shocks, that's what I use them for
-
What if you have a car that has the springs and shocks separate, could I buy shocks better suited for the lowering springs?

A couple comments, as an engineer myself, who has a significant vehicle dynamics knowledge.
1. Lowering springs developed for performance and not just looks, matched with an appropriate damper, such as a Koni sport, Bilstein, etc. can be used daily without much sacrifice. In many cases the car will have an improved ride overall (better control), with a slight increase in initial impact harshness.
2. Yes, increasing roll and pitch stiffness via springs can reduce mechanical grip, although load transfer remains identical if the ride height (and thus CG to roll center relationship) is unchanged. The caveat is that increasing roll stiffness, in particular, will often improve geometric control enough to where you do not lose, and can often gain mechanical grip by maintaining contact patch and reducing roll center migration. It also has handling benefits in that the car will respond more quickly to inputs. That said, you do want the softest springs you can get away with that maintain acceptable transitional handling in order to reduce sensitivity to inputs and improve compliance for imperfect surfaces, both of which improve usable grip and make the car easier to drive.
3. Wheel spacers with their own studs function identically to a wider offset wheel if they are hubcentric type. If they are not hubcentric, like the one you showed in this video, then yes, they put significant load to the studs in a way they were not designed to take. Hubcentric spacers transfer radial load to the hub bore with their own hub bore, and provide another external hub bore for the wheel to mount to, such that the studs are providing clamping force and not dealing with significant radial load, just as they did stock.
4. Camber kits can be an excellent choice if you have coilovers (many include them in their top mounts), or a matched set of performance-minded lowering springs and matched dampers. They allow for adjustment beyond what the factory tolerances will in order to get back to appropriate road-use settings (~1-1.5 deg negative).
5. Anti-roll bars can be an extremely effective tuning aid provided you do not go overboard. If you autocross, the Street class allows for one roll bar change. For most cars, due to their on-purpose, understeer-biased factory suspension tuning, a stiffer rear bar improves handling balance significantly without a big effect on ride quality, provided you do not go super stiff. You always want to exercise caution on anti-roll bar stiffness on the driven axles because you do not want to limit/remove load on the inside wheel. This is bad for any differential type, but particularly open diffs or torsen diffs. -
There are people complaining about this being boring?! Kids, this isn't SpongeBob. It's meant to educate you; not entertain you. Learn something; shut up.

I've heard you don't need to increase spring rate very much when you lower it if it is damped well enough because the roll centre is changed so the car rolls less, although that's taking into account the adjustments to scrub radius and bump steer etc..

i once saw a cat bite a guy in the neck like a tiger

I want to ask you about the lowering or racing springs on OEM dampers on DCC cars like 2015 GTI. As the shockabsorbers on DCC cars adjust dampning in millieseconds whyle driving and also allow the adjustment manually, then this looks to me like lowering springs might acctually work, i.e. Give a more sportier drive and lowering while keeping the negative aspects at bay because the dampers adjust to the new drive height and spring rate.
-
I understand his point on the lowering springs but I don't agree with it. Most lowering springs that lower the car 1.5" or so doesn't increase the spring rate a whole lot. And it won't destroy stock shocks. But when you go lower then 2" I do agree that it hurts performance and grip unless you get matching shocks and struts.

I'm so bored I don't oven know if I'm peeing
-
But what if we want the wheels to stick out a little say maybe 1/4" or 1/2" ?
-
horrendous lowering kit
-
Stance is all I care about.. ;)
-
I thought those clamps were to be used to help install / remove springs. I used them for that purpose only in the past.
edit: posted first then read the follow up comments and noticed this is 8 months old video. weird. -
How are wheel spacers different than offset wheels? There's still gonna be more leverage on the wheel bearings. It's pretty simple physics... Not sure what the big issue with them is...
-
sounds like you were gonna cum lmao
-
mercedes benz ABC suspension is pretty amazing. No sway bar and adjusts with hydraulic fluid... but expensive as hell to maintain
-
$200 for springs vs $700-900 for coilovers?
Thats a big difference specially if your just a beginner -
Engineering explained i have a question about the spacers my car came with a 6.5" wide wheel with a +40 offset the wheel i want to use ether comes in a +21 or a +51 offset in an 8" wide rim. planing on using the +51 with ether a 10 or 5 mm spacer to clear my springs. im hoping it wont throw everything out to bad. what do you say? its a 89 nissan 240sx with stock shocks and springs
-
If you DO match a lowering spring with a proper shock, then wouldn't most of the disadvantages go away?
-
What about a small 3" inch leveling kit? Is this such a terrible idea?
