Just go for the Emblems you like. I have replaced the LS trim-emblems on the Pillars with LS6 emblems My truck has an aluminum 5,7Block 11,5:1CR Truck-Norris-Cam, Headers and matching tune, that is pretty close to being an LS6.

Update on my Front-Brake Upgrade. Am Have bought some parts in the US and tinkered with solutions. As of now, I should be able to adapt the rear aluminium caliper and bracket to the front Knuckle and match them up with 14,88" Rotors from a 2020 Dodge Ram. This Idea came to me, because the brackets for the rear calipers space the caliper a lot forther out, and the additional rotor diameter would even out the lesser brake pressure due to the smaller pistons in the aluminium brake. I will have to get Adaperts CNCed that bolt to the Knuckle and the caliper bolts to. Because the bolt spacing is so much closer on the caliper bracket, than on the Knuckle that should work just fine. ATM I am waiting on a Rotor to get things going. Also I am checking to make the Aluminum Knuckles of a 2015 Silverado work on my RWD GMT800. Geometrically they appear to be spot-on. I will have to fabricate shims for the ball joints (taper angle matches, the aluminum Knuckle just has bigger holes. And adapt the tie-rod-ends a bit. At first I thought of using the inner ones also (they are beefier), but I am not sure if it is too much of a hassle, for no noticeable benefit. I will keep you posted, and maybe I start selling the brake-Adapters

Have you tried? The rotor diameter and thickmess are the same, as is the basic construction of both calipers. To get the bracket to fit would be lucky, but to mount the aluminum caliper to the sliders of the iron front bracket might be doable. That is why I need the measurement of the oem iron bracket for the big brake.

Thanks for the Input, but both of you have not really contributed anything new for me, or the measurements i specifically asked for. @swathdiver: we have pretty strict regulations (TÜV), I am aware of the Brembo Option, but ist is not realistic in several ways. @newdudeI know that all the front calipers from GM are iron, that ist why I asked for measurements to use the rear ones. I Run 8.5x18 oem wheels from the 2kxx Chassis. I upgraded the rear brakes to the 330mm dual piston ones from the suburban (These calipers are aluminum). I also checked clearance of the 4-pot ones from the 2019 silverado, but they do not fit my wheels, and the spacers that would be necessary are not TÜV legal. So I want to use the 330mm Rotors from the rear drum Brake gmt800 silverados, but will try to negate the weight Penalty by using the aluminum calipers. I am a trained mechanic with two decades of experience with american vehicles, racing, modification and Restoration. Unfortunately there ist very Limited Access to parts and relevant information in Germany.

@swathdiver I do not think this will be a problem. Yes, Aluminum expands more with heat, but Aluminum also dissipates heat much faster. Most High Performance brakes, designed for high temperatures use aluminum calipers. @newdude: I want to Upgrade the front brakes on my 2000 silverado. I have already upgraded the rear ones to the 330mm suburban ones. The calipers in back are made of aluminum, but the 330mm front brakes use iron calipers. I want to adapt the aluminum calipers to the front brakes.

Hi guys. has anyone yet compared the rear 2-piston aluminum calipers with the front 330mm brake iron ones? To me, it makes no sense why GM did not use Aluminum calipers in front as well. I assume that the caliper bracket does not interchange, but the caliper itself might. Here in germany it is pretty difficult to get a hold on measurements, but I have the 330mm rear brakes installed in my Silverado. So if noone has done the comparison yet, maybe someone with a rear drum brake Silverado can give me some measurenents of his front calipers. The most critical are: - spacing between the two slider bolts - distance between the outer area where the brake pad sits against and the area the slider bolt sits against thanks

Thanks, but here in Germany only an official letter from GM will be sufficient.

Hi, has anybody official GM written Data on the maximum load capability of the #20937769 wheels? I am from Germany, and so the TUV wants to have some official manufacturers data on the load rating. GM-Germany is not of help at all, and contaction GM-USA from Germay does not work, they will not answer me, because I have to go to GM-Germany... thanks
