I decided to switch to bigger disc brakes. These come in the Altroz diesel, CNG, and DCA models and are superb.
BHPian SavoyWalrus recently shared this with other enthusiasts:

A quick three-year update since I bought the iTurbo. The car has clocked 22k km since I bought it in December 2021, most of it driven in the city. I haven't encountered any issues so far, apart from an annoying rattle from the dashboard, which I plan to get fixed in the next service.
List of mods/changes I've made to the car since purchase:
- Michelin Primacy - Replaced it right from the showroom. Superb braking, low noise. One puncture so far. The stock XZ+ iTurbos came with 195/55/16, which is a little sharp for our pathetic roads. Will switch to 185/60/16 when I change the tyre next time. The Racer as well as the diesel Altroz come with this size.
- Momo Concave Wheels - The stock ones looked a little too plain Jane for me. Got the old ones exchanged for the Momos. No complaints. Got it resprayed recently after a few curb scratches. The original colour was Matt Black, this is Metallic Carbon Gray. Got the calipers painted golden.

- Code6 remap - Like most BS6 cars, the stock car is a little sluggish in low revs. Decided to get the Code6 remap after the expiry of my warranty. The best mod I've done to date. The car has oodles of torque and I can now stay a gear higher than usual.
- Bigger brakes - Like fellow member @CannedShroud, I decided to switch to bigger disc brakes, which was a fairly straightforward process. The iTurbos came with smaller 235mm discs, that weren't supremely confidence-inspiring. These bigger discs, which come in the Diesel, CNG, and DCA Altrozes are superb. This is what should have come out of the factory.
- Sunfilm - Recently added the SolarGard sunfilm, which is a Saint Gobain product. This is 75% and got them for all windows and the front and rear windscreen. Visibility is good and it keeps the car cool. Will report back during the summer.

- Damping - One common complaint with Tata cars is sound insulation due to the rather noisy engine. Remedied it somewhat with damping sheets on all four doors and the boot. Noise has reduced quite a bit. The place where I got it installed also has under bonnet damping sheet, which will reduce noise and heat. Considering that, but will have to do some research to see if it can keep the heat in check.
- Headlights - Stock headlights in the Altroz are pretty inefficient. Changed them for LED bulbs. They are quite an upgrade, but also considering new projectors.

Also, did a few "ricer" mods which I may cringe at and remove in the future.
The car was dechromed when it was given for a remap at Carmed, Bangalore. They did a good job, and I like how it has turned out. Another very "ricer" mod is the front splitter that I added. It looks nice, but I want side skirts to complement it, which I'm finding tough to find. Also, added a rear matrix turn signal indicator-cum-brake light. I don't know if I like or hate it yet.

Haven't done much to the interior aside from new floor mats, dashcam, and wireless Android auto adapter.

The car has served me well so far. It's easy to chug around the city, has superb straight-line stability on the highways, and handles decently well too. Fuel efficiency isn't great; sub 10 kmpl in Bangalore traffic. Another issue is the gearbox. It just doesn't slot properly, primarily between the first two gears. It does get easy to change after you get used to its idiosyncrasies.
What's next?
I may go stage 2, but I don't want a droney exhaust note when I go for a downpipe. I'd also like some coilovers because I feel the chassis has more potential. But, unfortunately, no one makes them. I've tried sourcing the Racer's front springs, which is the only difference in the suspension between the iTurbo and Racer, but no luck so far.
Would also like to figure out if the new Altroz's touchscreen display can be fitted into my car.
