8am for ulu yam drive is kind of late, as the road up to Gohtong jaya will be congested with lorries & slow cars. You won't enjoy the drive by waiting in vain to pass slower traffic. We usually meet before 7am at the foot hill just before the dam, (the drive is quite short, approximately 45 min.) then have breakfast at Gohtong Jaya or nearby.
For Kuala Klawang, which is the old road to Jelebu, NS, the drive can start on a later time as the traffic is less heavy. However, the view is better if you drive early, with the mist rising from the secondary jungle, it's beautiful. The drive is also longer. probably takes about 1.5 hr from ampang, if i remember correctly. The road is less well maintained compared to Ulu Yam, and it's full surprises. I remember one of the MINIs actually went air borne for a short moment after driving pass an elevated part of the road at high speed.
But these drives are fun, and addictive.
Better still, go to Sepang. It's fun and safer. May be can get HPC to allow a slot for the E9x, we need 30 cars though.:rock:
