Slim SL8 Front 8-Piston Big Brake Kit
The TTSPORT Slim SL8 is an 8-piston front big brake kit built around a narrow two-piece forged aluminum caliper. It pairs a staggered 28/32 mm piston layout with two-piece 380–405 mm rotors to deliver high thermal capacity, firm pedal modulation, and repeatable stops behind 19 in or larger wheels.
Why Builders Choose the SL8
Staggered Piston Bore
28 mm × 4 leading and 32 mm × 4 trailing pistons spread clamp load evenly across the pad for stable bite and reduced taper wear.
Two-Piece Forged Aluminum Body
Higher stiffness-to-weight than cast calipers; 5.20 kg per caliper without pads.
Heat-Insulated Pistons
One-piece heat-insulated pistons with dust boots limit fluid heat soak during back-to-back stops and protect seals from grit.
Two-Piece 380 / 405 mm Rotors
Internally vented, left/right directional, with iron/steel or carbon-ceramic options for street and track-day duty.

| Bedding-In Procedure | Required before normal use | |
Iron/steel rotors suit aggressive street and track-day use. Carbon-ceramic rotors reduce unsprung mass and resist fade in extended high-temperature work. Friction values vary with temperature, line pressure, and rotor condition. Pad and rotor materials must be matched — never run iron-rotor pads on a carbon-ceramic disc.

Will It Fit? Your 3-Step Check
Wheel fitment is not universal. Always verify spoke clearance, caliper window depth, and wheel offset against the supplied caliper dimensions (391 × 128 × 144 mm) before ordering. Send wheel specs and your vehicle details to our team for a clearance check.
1. Wheel Diameter
19 in or larger wheels are required.
2. Spoke Clearance
The SL8 requires a minimum 90 mm spoke clearance.
3. Vehicle Model
The SL8 is a platform-adapted big brake kit. Confirm your year, make, model, and wheel specs with our team so we can ship the correct bracket and line set.
Installation & Break-In
- Installation should be performed by a qualified brake technician.
- Caliper mounting uses radial mount with vehicle-specific brackets.
- Brake line fittings are vehicle-specific on both caliper and chassis sides.
- A proper bedding-in procedure is required to transfer pad material to the rotor face and stabilize friction before normal use.
- Skipping bedding-in can cause uneven friction, vibration, and reduced bite.
- Pad and rotor materials must always be matched.
Frequently Asked Questions
What wheel size do I need to clear the SL8 caliper?
19 in or larger wheels are required, with a minimum 90 mm spoke clearance. The slim 128 mm caliper width helps, but every wheel design is different — verify clearance before ordering.
Why does the SL8 use staggered 28 / 32 mm pistons?
Smaller leading pistons and larger trailing pistons spread clamp force more evenly across the pad. This reduces tapered pad wear and gives more linear pedal modulation under repeated braking.
Should I choose iron/steel or carbon-ceramic rotors?
Iron/steel rotors offer strong bite, excellent value, and hold up to aggressive street and track-day use. Carbon-ceramic rotors cut unsprung weight, resist fade longer at extreme temperatures, and last significantly longer — at a higher price point.
Is this kit a direct bolt-on for my car?
The SL8 is a platform-adapted big brake kit. Calipers, brackets, and brake-line fittings are matched to your specific vehicle. Confirm your year, make, model, and wheel specs with our team so we can ship the correct bracket and line set.
What pads ship with the kit?
Pads are matched to your rotor choice. Iron/steel rotors use a 0–600 °C pad with μ ≈ 0.38. Carbon-ceramic rotors use a CCB-specific pad rated 0–700 °C with μ ≈ 0.45. Pad and rotor materials must always be matched.
Do I need to bed-in the brakes?
Yes. A proper bedding-in procedure is required to deposit an even pad transfer layer on the rotor face. Skipping it can cause uneven friction, vibration, and reduced bite.
Ready to spec your SL8 build?
Send your vehicle, wheel specs, and rotor preference. We'll confirm clearance and the correct bracket/line set before the kit ships.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2.
Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.

delightful read
Format: Kindle
What a delightful read. The characters are awesome, the plot was so good, I loved it. I was intrigued and it kept me wanting more. Told in multiple pov, the book sucks you in and doesn’t let go. I cannot wait to read the next book.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.

A Beta Worth Rooting For
Format: Kindle
In Spare, Violet Fox flips the omegaverse on its head, giving us a Beta heroine determined to make her mark. Joining the Beta Trials to support her sick father, she's thrown into a pack that doesn't want her, especially the possessive Alphas.
But here's the twist: their sweet Omega turns out to be her scent match. Cue the angst, forbidden tension, and a slow-burn romance that will make your heart ache in the best way.
Violet Fox delivers an emotional, refreshing take on the genre, proving Betas aren't "spares." They're stars.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger
