Tamiya 54965 TT-02 RCType-S Alum Steering Set (Long Tie-Rod) (https://www.tamiyausa.com/shop/optio...-steering-set/) is designed for the S type kits

Tamiya 54752 RC Steering Upgrade Parts (https://www.tamiyausa.com/shop/optio...upgrade-parts/) can be used on ANY of the TT-02 on-road kits

I have both of the Tamiya aluminum steering upgrades on my TT-02 S kits. I feel the long tie rod set has less bump steer. Ackerman is also easier to adjust. Here is a decent review of 54965 the The RC Racer website...https://www.thercracer.com/2020/10/5...-aluminum.html

One thing that I would recommend is that if you use Tamiya 54752 is that you use a 3x23mm screw (inserted from the bottom of the chassis) and a thin locking nut to attach the steering posts to the chassis. You can see this being done on page 14 of the TT-02sr manual. The long step screw that acts as a steering post on the basic TT02 can get ripped out of the chassis in a big collision. While this isn't a big deal if you are using a stock chassis, it can be very difficult to replace one of the colored chassis (red, white, or blue) and it can also be hard to get a carbon reinforced plastic chassis at times.

I hope this information helps.

There are plenty of aftermarket companies that make aluminum steering racks for the TT-02 that are similar to the Tamiya 54752. The Yeah Racing kit gets good reviews and is less expensive. There are also aftermarket companies that make steering racks for the TT-02 that offer extreme ackerman angles which is good for drifting.
