Re: Atom 3.5r Geometry and Alignment Setups

Hi! I tried a lot of setup on mine. Only track use. I have ariel’s geo but with more camber. Front: 0.18° toe out , 2,5° camber (max with the same value R/L) Rear: 0.25° toe in, 2.8° camber (max with the same value R/L). You can choose more toe in for the rear, to avoid to much oversteer. But overst...

Re: Tyres, Yokohama A052 or Avon ZZS or alternative

Nankang AR-1 are very good tyres too, but don't exist in 245/45/16 (only 225). They are more progressive than khumo V70's. But i don't understand how can you run 5 days with the rear. 3 Days are my best, which ever brand i use. I try Toyo R888-R (very good, need low pressure), Khumo V70's (HArd/medi...

Shoulders are very square on 210-580 Then, i try 190-580-15 Front (same) 230-630-16 Rear I find it better, the engine doesn't suffer (it works even better, maybe because hi...

Re: Setup sheets

Well, it doesn't mean anything if rear toe is different. On the Front, i have what Ariel recommands, and i think it's fine. On the road and with no camber, maybe toe 0 is ok, i don't know. I try once but never pleased me. I have less toe than ariel preconizes on rear, and my car turns very quickly. ...

Re: Atom fuel tank removal

Hello!
2 bolts at rhe top edge, and 2 others on the back at the bottom from memory.
It comes out through the bottom when the engine is still here, not easy, but maybe you could try through the top.
