Default Vogtland Springs/Koni STR.T reviews

Just thought I would give a review of the springs I installed on my 2013 GT/CS. The car is a daily driver and has to ride well while not being harsh. It has the stock 19's and awful Pirelli P-Zero Nero 245/45/19's.

I bought the Vogtland GT Leveling Kit. .8f/1.2r and Koni STR.T's(Yellows), a J&M(Founders Racing) Panhard bar and Eibach camber bolts.

Vogtland is the maker(my understanding) of the Steeda Ultralight springs.I believe the spring rates are slightly different but not by much and of course the drop amount is different.
Vogtland lists 4 kits..A V6, A V6 Leveling, a GT and GT leveling each with different drops. It is my understanding that the way they get the different amount of drop is with different front spring rates. The rears are all the same.

I got the Koni STR.T's at Hypermotive performance on sale.

This is the panhard bar I used. It is made by Founders Racing and seems to be a good quality piece with grease fittings and easy adjustment and Poly ends.

And last but not least the Eibach Camber bolts. I think enough has been said about those.

Install was easy and I am VERY happy with the drop and the ride. The camber was -1.7 and -1.5. The bolts brought it back to -.5 on both sides so well within specs
The car sits at 28.5 front and 28.5 rear with a full tank of gas. The drop was exactly as promised.
Much less body roll, less brake nose dive, better cornering and not ridiculously low.
I have noticed less noise from the crappy Pirelli tires going over expansion joints, bumps etc.
Now to the ride....the stock springs and shocks were, in my opinion, very abrupt during suspension changes. It rides SMOOTHER THAN STOCK. Now that is not to say it isn't firmer than stock. But no harshness, just feels better. It is hard to explain ride quality in general but I am extremely pleased with the results.

All together I put app. $700 into it and I love it.

Hope this helps if you are considering lowering.

Nice stance you have there. I have the ultralights myself, but I didn't get the 'leveling' effect from them. Rear still sits visibly higher than the front, but the overall handling was the primary motivation and in that respect I'm perfectly happy.

Here's a pic of how my car sits with the Steeda springs (and koni sports)

Thanks..I thought long and hard about the ultralight springs but just didn't like the drop amount or spring rates..When I reread my review I guess I should have said that Vogtland makes the ultralight but that is where the similarity ends..lol..different drop and different rates.
Here she is after about 750 miles on the springs and shocks. Ride quality is awesome. It truly does ride smoother than stock and handles 10 times better. Somehow the car feels lighter..crisper going into and out of the turns.
Only issue I have had is I had to remove the pan hard and install 45 degree grease fittings. The ones that came with it I couldn't grease once it was on the car and it started creaking.
