i can see what you mean but ,i just cant resist a nice set of bridgestone eager traffic accidents , on some nice fat 13 inch jellies !! nice

and a guy i know found a full set of 345/50/13 eagers in the shed of his new house ,but he wants $1000 each !!!

and the the only fat 13 inch tyres that i can get are michelin tb15s which are 470 each (buyers price) and they dont realy last long so ill wait untill i actually need them

Ronald................the drifting competition now makes sense.

Another wrinkle besides tire compound is heat range. If you were to run say a 265mm front it would likely never warm up. My son runs a Kart at local Autocross (Gymkhana) and on really cold days we'll pump the tires up for a smaller contact patch which puts waaay more heat in the tires so they get up to temp and offer more grip.

On my road race coupe I run 27 psi all around.

If you can find a LSD get one, this past weekend at a track day coming off a second gear hairpin I could do drifting exhibitions no problem (The car has a 4.11 LSD and 4 speed close ratio gearbox)

I'd have top do the math but I believe the lower profile 185/13 vs 155/12 would offer you lower gearing.

On the rear sway bar it'd be really easy to fit one off another car; the 1200 rear bar bolts to the chassis rail just ahead of the rear tires and then clamps to the leaf spring. I think you might be able to purposely fit a larger rear bar for oversteer.......................simply leave one side disconnected for daily driving then when you arrive at drift competition bolt the one side up (you only need to disconnect one side). When we have heavy rain races I disconnect both sway bars to get more bite...........takes me about 2 minutes tops.

Hi Rallytwit,Wat tyre pressure u reco to hv more grip?

In malaysia i think almost like no ppl equip their 1200 axle with lsd(coz is hard to get + expensive). Most ppl rather put ae86 axle.

Do u hv any pix related to the rear sway bar??

Thanks again...

Jmac,i already check my lower arm n is not parallel with the road. I dunno how to say but the body is higher than the tie rod end. So when cornering i still get better -ve camber.

Tried 40psi wif 185/60r13 on the frt for few days. Felt quite responsive on dry surface compare to 30psi. Might bcoz less contact area thus less steering effort. Still din get the chance to test on wet road yet. I think might get better result wif 40psi on the frt.

BTW 165 can perform same as 175 tyre on the frt? Coz 1200 r quite light. 165 hv lower profile so might increase handling.

Juz change the frt tyre with Yokohama A.Drive 175/70R13 with 30psi.
Feel more grip on wet surface as my 185/60R13 were 5yrs old rubber.
But is jus slight improvement.
Would it b my suspension problem??

Sounds like its over sprung and too stiff and probably next to zero suspension travel. I would imagine if the front has also been lowered to the ground too much the roll center is way out also.

The travel is like juz 2inch. Might b too stiff spring coz i use S14 rear spring.
