Want tires to last longer? Reduce weight.
Want brakes to last longer? Reduce weight.
Want to decrease braking zones? Reduce weight.
Want to increase acceleration? Reduce weight.
Want to reduce shock wear? Reduce weight. (you could lessen spring rate, thereby transferring some of the damping duties to the spring, but the resultant is potentially excessive body roll)
So how does one go faster cheaper? Effin' diet for you and your car!!!
And Hoosiers.

Nice, how did you do?
We are running the Chump car race at VIR at the end of the month, will you be there?
I almost shed a tear that sunday when I saw our car fly through the straight passing left and right while making wonderfull Pfhhhh!!! turbo sounds! Just the thought that everything in the car was held together by JB, gourilla tape, and zipties while watching it go fast made me a bit sentimental I mean, the compressor outlet and one of the engine mounts was essentially JB mixed with aluminum piping. Just the fact that that was not the weakest link was shocking on its own.
So the car ran for about 2-3 hours on sunday untill we lost all the water due to the leak from the back of the engine (still need to diagnose it). The car came in the pits red hot with no water in the cooling system AT ALL! Surprizingly, the engine still ran and had power. So we just waited till the last 5 min of the race and send it back out to finish the race. All the water was gone in a matter of 2 min, but again, the engine held up and we finished the race.....in the second to last place So besides that loosing water issue (and also shooting the exhaust off due to backfire...and bad bearing....and some other stuff) everything was dandy!
At this point the plan is to assess the car's condition and to deside on either fixing it or building another car.....
If there is anyone on here that would be interested in taking part of renting a big warehouse space to store and work on cars please let me know. We are trying to reach that "critical mass" of people to make the idea feasable.

Where would the warehouse be?

I used them once at SP Shenandoah during TD on a wet track and it was not pretty. But my thread depth were pretty bad though already and Shenandoad is known to be one of the slippiest track while wet.
Highway driving on a moderate speed of 75 or higher on heavy downpour is no problem at all, traction is very confident with a good thread of course. Most tires are rated 55MPH to start hydroplaning.

How are the star specs in the rain?

Full tread Starspecs are very good in the rain. Once they are more than 30% worn their performance drops off sharply.

Question: If you have a separate set of rain tires/wheels, is it a good idea to run the 255 width? Or would it be more beneficial to run a 245 or even a 225 on an 8" wheel? From what I have heard, the wider tire can increase the risk of hydroplaning, so does that play a part?
Now, a tire can only evacute so much water. If the amount of water trapped under the tire exceeds this, hydroplane happens. So to correctly answer your question, the actual tire in question must be considered. All things being equal, wider is definitely not better in standing or streaming water. Also remember that alignment and suspension setup play a huge factor in wet traction. Soften shocks. Up tire pressures. Must of us won't change an alignment at the track, 9kI4 (Matt) excluded , but that would be optimum.
Another consideration for some of you- if you have aspirations of TT'ing or racing down the road, look at the rules and/or point assessments. Running a 255 makes no sense from a point standpoint in TT's when the benefit in time is nearly immeasurable. Use the point(s) elsewhere, like weight reduction. Racing spec's the size.
Wanna go fast? Weight reduction. Everywhere. Wheels (rotating mass). Battery (up high and in front). Etc.
Want tires to last longer? Reduce weight.

Want to decrease braking zones? Reduce weight.
Want to increase acceleration? Reduce weight.

I need some ideas on reducing weight. Not to myself, if I did, I would disappear if I turned sideways, I mean to my car. I removed a lot of the interior and stock bulkhead but added a heavy duty rollbar that negated weight savings. I swapped the radiator out for a very lightweight aluminum one, but since the capacity is so much more I added back a lot of water weight.
