Any additional info from those that have installed them? Any rubbing issues? How is the ride?

Going to bump this in case some want to chime in. Also looking for info or a review from someone with wider wheels up front

I can't tell you anything useful about tire/wheel clearance, but I can tell you that you will clearly feel the difference that quarter turn adjustments make. If you have no idea where to start, set them full soft and go up in 1/4 turn increments. Back off an eighth turn when it just starts to be a little too firm or harsh for you. Don't be afraid to use different settings, front vs rear, so pay attention to which end is getting firmer faster.

If you're tuning for cornering/handling performance, you can follow this piece that I've snipped out of Koni's tuning suggestions for double-adjustables. Yellows don't feature bump damping adjustability, but you can use the same approach for rebound adjustment tuning. I've edited out any references to bump damping to avoid confusion here.

Adjusting the REBOUND Damping Control
The rebound damping controls the transitional roll (lean) as when entering a turn. It does *not* limit the total amount of roll; it *does* limit how *fast* this total roll angle is achieved. How much the vehicle actually leans is determined by other things such as spring rate, sway bars, roll center, ride heights, etc.
It should be noted that too much rebound on either end of the vehicle will cause an initial loss of lateral acceleration (cornering grip) a that end which will cause the vehicle to oversteer or understeer excessively when entering a turn. Too much rebound control in relation to spring rate will cause a condition known as "jacking down." This is a condition where, after hitting a bump and compressing the spring, the damper does not allow the spring to return to a neutral position before the next bump is encountered. This repeats with each subsequent bump until the car is actually lowered onto the bump stops. Contact with the bump stops causes a drastic increase in roll stiffness. If this condition occurs on the front, the car will understeer; if it occurs on the rear, the car will oversteer.
STEP 1: With rebound set on full soft, drive the car one of two laps, paying particular attention to how the car rolls when entering a turn.
STEP 2: Increase rebound damping three sweeps (or 3/4 turn) on all four dampers and drive the car one or two laps. Repeat Step 2 until the car enters the turns smoothly (no drastic attitude changes) and without leaning excessively. An increase in the rebound stiffness beyond this point is unnecessary and may result in a loss of cornering power. Note: This point will probably be reached at one end of the car before the other.
However, individual drivers may find it desirable to have a car that assumes an oversteering or understeering attitude when entering a turn. This can be easily "dialed-in" using slightly excessive rebound settings at either end.

Very nice! I'll be sure to save this. Looking to go to 19' wheels and the drop from the Koni's would be perfect until I decide to get lowering springs or coil overs.

I might have to be the Guinea pig to see if you can run Koni's up front with 20x9 w/ 275/40 tires. Hmm...

anymore feedback from people using koni yellows, like them?

I have the Koni Yellows and have some thoughts in my autocross build thread: http://www.camaro5.com/forums/showthread.php?t=456227

Got them for autocross purposes. Still tweaking rebound but they certainly do better under compression than the 1LE shocks.

Copy & Paste:
- Koni Yellows are a definite adjustable upgrade to the 1LE shocks. Full soft is softer than the 1LE shocks and full firm is much firmer. Haven't done enough testing yet. Due to the weight of the car and soft springs, I'm skewing towards setting the shocks softer than firmer.

- Compression on the yellows is higher than the 1LE shocks. That isn't adjustable on the Yellows but is a welcome improvement. A bit less lean when hard on the brakes.

- Max camber doesn't rub. Couldn't get equal max camber left and right. Front was -2.1 or more. Rear was -1.3 or more. Expect to get equal camber as the new parts settle into place.

- Didn't notice a height change from stock due to change in tire diameter as well.



Part #s:

2x 8241-1292Sport

1x 8741-1563LSport

1x 8741-1563RSport

Off-the-shelf valving for now

Thanks for the review. Do these actually change ride height at all if tire diameter is left unchanged? I have seen mixed reviews on that.

Great. So your stock 1LE wheel and tire fit with the KONIs no issue. Then as long as a 28" diameter tire fit I am good. Can you please post pictures of the front tire wheel clearance?

The question as to whether or not the Konis change ride height or not can be directed to one post from a new member's FIRST and ONLY post. Not very reliable.

http://www.camaro5.com/forums/showpo...&postcount=128

Since the SCCA views them as legal within certain classes that do not allow ride height changes, and others have offered feedback of no change, it sounds like you get the same as stock.

Can someone with a stock 1LE with 285/35/20 tires measure the distance from the ground to the top of the wheel well?

I'll be back with my Camaro this Friday and can compare then. My guess is that the ride height is the same. Technically, the ride height can change a bit due to the internal shock construction. This is despite having the same physical specs.

I have the BFG A/S 285/35/20 tires on my car now so I measured all 4 corners.
Interestingly, the LF was 29.0, the LR was 29.0, the RR was 29.0, but the RF was 28 3/4 in. The car is in the garage which is fairly level. So there you go. Hope that helps. I am contemplating the Koni's for this autocross season, but not too fond of the idea of cutting holes in the trunk.

find out what the LF is with you in it

A perfect comparison then! I have the same tires on my 1LE. My garage is a little bit slanted so I didn't get too accurate. The answer is 29" on all sides! So no height change with the Koni Yellows.
