I got a TT-01 with a HPI 190mm STi body on it, heres a picture. Right now I got 26mm wheels on it and they are to sunk in for me, how much offset do you think I need for them to become more flush with the body? Or are there any way to add a spacer to make these wheels work? Need them out about 1/4" more.

On a side note, anybody know where I can get one of those headlight and tail light kits that I see you guys have?

I'm guessing about +8mm on top of what they are should sort you out, best if you measure it with a good ruler though, and bear in mind if they stick out at all they will rub on the shell.. If you have a look in your bits you might have some wider wheel locator things, the ones that go behind the wheels and are held by the pins. I got some with mine, but only a pair of them.

light buckets from a Yokomo Subi first generation will be a pretty close fit, you can get them at genkidoridori or banzaihobby. If you want to bling out a shell with lights, HPI is not the way to go, they don't make light buckets, some of their shells come with lexan light buckets but these are no where near a chrome plated light bucket from Yokomo, go with a Yokomo shell or even a tamiya shell that comes with light buckets.

you need some off set wheels 9mm rear 6mm front

Yip if that is really a 190mm body (That looks like the WRC scoob that was released in 190 and 200mm) 6mm in front and 9 at the rear.

If it is the 200mm then you going to need like 7-8mm in front and 10 at the rear. Don't think you get more than 10mm......

what width do you guys suggest? I got 26mm right now, seems like most of the higher offset wheels go to 35mm.

From what I've seen all wheels are 26mm but offered in different offsets. Have yet to come across a 35mm wheel listed for a 1/10 touring/drift car.

26MM is the size of the width of the wheel not the offset, the offset is what space you create from the chassis

Hpi Super Star wheels come with the offest hexes that fit inside where you mount the rims to hex hubs then chassis. I really needed those because stock, the wheels were so far sunken in on my shell it was crazy I have an Hpi 200mm Nissan Silvia S15 and its already a really wide body so putting in those rim spacers made my tires become flush with my shell without rubage, and it now looks just as it should. Oh and I had to buy the wider 6mm aluminum hex hubs just for this to work as it was, and they were surprisingly cheaper than the 4mm hex hubs in aluminum, but the smaller set came with a bunch of shims and an extra hex hub so I guess thats why but I hope some of that helps you.
