Are you looking for a touring car, or a drift car? The Sakura that you mentioned is a drift car, and, not a very good one at that. It needs a bunch of upgrades, such as bearings, since it comes with bushings, and the plastic is a bit weak. The belt is also not the most durable, and can get pricey quick to keep replacing. I'm not sure why you want a kit, since there are some decent low cost RTR's available, but, if you are dead set on a kit, i would look at Tamiya, but, they can get pricey to make durable and worthy of actually using. From a ton of experience with the cheap stuff, i learned many times the hard way that cheap isnt always the best option. You would be better off with something like a Lightning EPX or STK from Redcat, or the Exceed RC equivalent. They only come RTR, but, they dont need a lot in the way of upgrades out of the box, and, when you do need parts, they are cheap. The downside is, not a lot of hobby shops carry the cars or parts in store, so, most stuff for them has to be gotten from Amazon or eBay. This is my go to for drift and touring cars:

It comes as a drift car, but, with a tire and pinion swap (keep in mind, they are MOD 0.6 gears), are easily converted to a touring car. You can also find them as rollers and sliders on eBay under the Redcat (Lightning STK and EPX), Exceed RC (Drift Star, avoid the Mad Speed cars, they are garbage), and HSP (Flying Fish, 94123, 94103) names.
Disclaimer: I am a huge fan of the HSP based cars, and have no issue with buying used rollers and sliders, and building them how i want, but, there are a lot of people who, for one reason or another, really dont like these cars, so, before buying one, if you have any questions, ask away. Unfortunately, unless you are willing to wait months for stuff from China, there really isnt much out there in the way of cheap on road kit stuff.
All of MST's cheap cars are 2WD, and not really good ones at that, unless you are strictly racing indoors on carpet. On asphalt and concrete, they dont work well as a drift car, and, to make them into a touring car, they are too slow, unless you find a way to completely regear the rear diff, since its geared more for drifting. I had 2 of them, and, since I'm not into drifting, i always convert drift cars into touring cars, and, no matter what i tried, it always wanted to drift, until i slowed it down below 18MPH, and, on rough concrete, it tended to hop around a lot.
