EVO GR4
Four-piston gravity brake for the most demanding applications.
Delivers maximum power with no compromise. Super-smooth lever action and premium construction make controlling that power feel natural. The benchmark brake for gravity and e-bike use.
- One piece machined caliper for reduced weight and increased stiffness
- Four hybrid pistons allow smooth movement and excellent heat management
- The largest pistons for the greatest power
- The larger pistons increase the ratio of the brake by ≈ 6% when compared to Tech 4 V4 brake system
- Improved caliper stiffness increases power and control
- Not compatible with vented rotors
- Revised bore cap design reduces width for more frame clearance
- Choose this caliper for ultimate power in the most demanding applications
The Lever Blade
- There are 3 different lever blade options.
- Brakes are supplied with Standard (STD) lever blades, this blade will be the right choice for the majority of users and applications. POWER and CONTROL options are available separately.
- All EVO blades feature an increased lever hook for greater control and security during aggressive riding and a new dimple design in the finger contact area to improve comfort during hard braking, while still retaining grip in all weather conditions.
- All blades also allow reach and bite point adjustments.
Cam Mechanism
- A new cam designed to decrease the free lever stroke while maintaining the feel and modulation in the braking zone — a key feature of the Tech 4 brakes.
- The result is a slightly firmer feel at the bite point, followed by a gentle rise in power through the braking zone, further enhancing brake modulation.
Piston Movement
- Roller bearing main pivot is carried over from Tech 4 along with sliding guide bush on the main piston.
- Additional secondary guide bush keeps the piston running perfectly straight to maintain super smooth piston movement throughout the full lever travel.
Bleeding
- A bleed port has been added to the master cylinder body to allow bleeding without removing the lid, simplifying and streamlining the process. The classic "open" bleed option is retained for the ultimate bleed.
- The internal port design has been reworked to eliminate air pockets during bleeding and to support a more consistent bleed process.

e46 Sedan Black Kidney Grill: Good fit with a better attachment mechanism than stock!
Size: For BMW E46 1998-2001
These kidney grill replacements were for a e46 sedan (323i). They fit really well. They come with a different type of attachment mechanism than other types I've used in the past: These have 'posts' with a slight groove that you gently pry into place against the hood's mounting tabs. It's a solid holding mechanism - much better than the tab-types I've seen in the past. These do not wiggle around, and feel very solid once mounted. They DID require a bit of fitting with a dremel where the hood release latch is mounted to the hood. I had to cut back about half-an-inch of the inner 'shell' of the grill so it didn't interfere with the latch when you pull 'up' on it to release the hood. Based on having an e46 sedan for 16+ years, and having replaced the kidney grills several times, I'm quite fine with a little bit of modification for a good fit. I like these quite a bit better than other aftermarket types, and even the OEM BMW grills. The price is good, and mounting is solid. I liked them so much, I purchased a second set for my son's 323i right after putting them on one of my 323i's.
I plan on getting a set for a 325Ci one that car needs replacements.

They fit super snug and the quality is way better than price suggests.
Size: For BMW E46 2002-2005
They came in wrapped very well in foam and bubble wrap. They felt sturdy and the matte finish was satisfactory. They needed quite some pressure to snap in but when they did you could tell they weren’t going anywhere. The fitment is perfect and it looks great. If the stubs in the car where the grille clips attach are in tact you shouldn’t have a problem. Don’t be discouraged by the negative reviews.

Good value for the money
Size: For BMW E46 2002-2005
The matte is flawless and looks pristine & super easy to install. It does fit and it’s a good enough fit for a daily driver; however, it’s not a flawless fit. It’s off by maybe a 1/16th on the inside corners. It’s amazingly close despite the price point…would definitely recommend.

VERY poor materials and fit for E46, WILL FALL OUT
Size: For BMW E46 2002-2005, Size: For BMW E46 2002-2005
This part resembles the original, but not enough.
It is both too big AND too small, depending on the dimensions. It's too small from top to bottom, and too big from side to side. The locking tabs don't get close enough to lock (see pics) because there is too little clearance. Viewing from the front, the outer top corner is so far out (see pics) that the most important tab cannot properly lock in, causing the grill to drop out into my hand (or the ground, if I wasn't there to catch it). The grill also is missing some important curves to follow the shape it is supposed to fit into.
It also wasn't matte black as ordered. It looks like it was spray-painted, but I can't be sure. it is made of VERY brittle plastic, and the locking tabs are VERY small and flimsy. I wouldn't expect this part to survive a month or two before blowing away in a medium breeze.
One positive is that there is a relief cut to allow the hood safety catch handle to move fully upward without interfering with the plastic grille. That one positive has a lot of making up to do, and there's no way it can do it. Add to that that the seller included instructions for a car fifteen years newer than the model advertised on the item page, and we have a complete failure. But don't worry! I'm sure the seller will probably delete the listing and make a new one so they don't have to have this honest review attached to it.

Quality grills for e46 BMW
Size: For BMW E46 2002-2005
No reason to buy replacement grills at the dealer or even at an auto parts store. These are great quality for a fraction of the price...and you get both sides. Highly recommended if you have an e46 and the grill plastic has deteriorated and is loose. These grills are thick and robust. I like them better than the original. Fit is snug but they look great.
