Increased costs of the tyres is not just because of tyre wear due to loss of traction, the 92 is not the same quality tyre therefore needs to be replace more often. We know this through our use of both tyres. Different shocks and springs will help to get the power down through the 92 with the different offset rims. So we can the buy tyres more often, buy more springs, more shocks, more rims, and more tyres to get different circumferences so how is that helping with the budget when we have our tyres lasting longer now, and don't need to buy as many shocks and springs. Once a couple of people start adding the extra components to run other will follow. It's not always about the big HP numbers. Correct setup will is more valuable. Even in the USA they will run the small blocks at particular big block races and take the points penalty for running the small block as they believe it is to their advantage. I am not sure if you know or not in the engine development side of things but the DMA is working towards bringing in a engine for the open division which will be more cost effective, and readily available. We have appointed one of our technical officers to do a full investigation and a trial may happen shortly. You can't just single out a couple of issues with the dirt mods and says if these change everything will be good. You have to look at the overall package. The DMA is moving forward in the direction that it believes will benefit its members. That's why a few change have been instigated: we have the new sportsmen section, new junior Dirt Modified division, a few changes made to specifications, and now the investigation of a future engine. I think the DMA is moving in the right direction to benefit its members. I knew you raced dirt modifieds a while ago before we joined them. It is a great class as u said. But with all things progression happens. Some people like progress some don't. [U]"However i speculate that the bigger HP car of Robbo,s car may become a bit of a handfull even for such great driver and therfor loose a few tenths from his best times."[/U] How can you say that? We and the rest of the big block racers put the 467 big block with 900hp through the small tyre it handles it and car is not too much of a handful. So how can you say that the tyre will make the cars be a handfull for the so called bigger HP engines in our class at the moment? Cheers Jane.
