Practical Corner Weighting: 3. Initial Corner Weight Measurement
3. Initial Corner Weight Measurement
01.49
00:00 | - We're now at a point where we can load the car up on our scales and get our initial corner weight measurement. |
00:06 | This is of course going to tell us what our starting point is as well as give us some guidance as we move through the following steps of the process. |
00:13 | Here we can see that the corner weight scales straight away show us the weight on each corner of the car, our total weight now sitting at 1360 kg, remembering that we've added 84 kg of ballast to replicate the weight of the driver. |
00:27 | If we choose the left rear corner as well as the front right corner, this will now display our cross weight which we can see is 662 kg. |
00:37 | Expressing this as a percentage will round that to 48.7%. |
00:42 | So we can see that our cross weight percentage is a little low, we're a little bit lighter than our target of 50%. |
00:48 | We can now dive in into a little bit more detail and see why that's the case. |
00:54 | Looking initially at our front axle line we can see that our right front corner is a little bit heavier than our left front. |
01:01 | Now as we discussed in the body of the course, this can be a problem for our braking performance, particularly in sensitive chassis with no ABS. |
01:10 | In our case the car is relatively softly sprung and we do have the benefit of ABS so this isn't necessarily a deal breaker for us but it is a consideration. |
01:20 | The bigger issue we actually have with our cross weight percentage is a result of the rear axle line and here we can see that the left rear weight is significantly lower than the right rear weight. |
01:32 | These are the sort of things that we need to take into account when we move through the following steps of our process and we start ballasting the car to suit or alternatively adjusting our ride height. |
01:42 | For now though, let's continue with our process. |
