tire sizes
i thought i should share some valuable info. first, '97+ dodge avenger wheels fit svx's from 15 to 20" akuza creations. today i fitted 245/50-16 tires. there is 2,100 lbs over the front wheels which is equivalent to a ferrari 612 scaglietti with 50/50 distribution and 245/40-19 front tires, which are equal to a 245/50-17 ('08 acura rl) or 245/45-18 (jag xk8). the height is crucial for response dynamics, especially in autocross. also, the bmw m6 uses 255/40-19 front with close to 2100 lbs front. i'm converting to rwd and 255/50-16 rear tires-think bmw m3 255/40-18. also ccrengines.com has aircraft quality 3.3L with a 3 yr/36k m warranty and custom cams for $3,605. today i bought a set of enkei wheels with falken z rated a/s tires for under $800 from discounttiredirect. tomssvx is the chief engineer and i have alot of faith in him.

I'm sorry but I find this post is difficult to read. Yes a number of cars use the same 5x114.3mm (4.5") bolt pattern as the SVX. I'm confused by your statements on weight distribution on the other cars you refer to compared to the SVX. While our front end end weighs close to that figure the rear is much lighter and we are nowhere near 50/50 front/rear balance.
I agree the aspect ratio and subsequent tire height is crucial to response in autocross as I do it regularly with my SVX (including this Sunday), but I'm really lost by the rest of your post Todd

tires sizes
the rear weight is irrelevant in a front heavy car. 75% of the braking is in the front and all the steering and control is in the front unlike a porsche you can steer with the throttle with the heavy rear. for example the new fwd monte carlo v8 uses 255 front tires and 235 rear tires. understeer is the issue, not oversteer, but i prefer the wide look in the back, but for autocross you may want to go narrower in the rear for balance as a porsche 60/40 does in the front: '92 911 turbo 255 rear, 205 front. i've also found that going lower profile than a 235/40 is not good for autocross, so ideal tire sizes for autocross would be 245/40-19 front and 225/45-19 rear.

rear weight is irrelevant???? Uhm not really. Rear weight helps the balance and in a way can help with understeer. If you have a better balanced car (weight in the rear) you can do things to promote oversteer and eventually get a car that breaks away evenly in corners. Also, no offense but nothing about the tires that you mentioned is new. Do a search and you will find that wheel fitment and tires is one of the biggest topics of discussion here.

a smaller rim is also more ideal... a 17" rim with stock diameter tires are very effective

smaller rims
the porsche cayman comes with a 205/55-17 that can be use in the rear instead of adding wieght to balance a car which is never good. an svx would weigh over 4200 lbs. balanced. actions always speak louder than words.

HUH? You are best off with some 245/255 with a moderate sidewall. There are things to do like moving the battery to the trunk to try and balance some more weight. There is also ditching the ABS/washerfluid tank & pump/ air conditioning/ auto for a 5mt to lose more weight off the front. also the fiberglass hood will shave som ppounds up there Tom |

response was to all replies
someone suggested adding weight to the rear to balance the front

not adding weight, merely working with the bias we have... Under the right conditions with an experienced driver, it has become very easy to oversteer the SVX. It is called tail braking and will be your best friend or your worst enemy if you cannot control it.

tire sizes
i decided to keep the awd because there is not much change in weight. the awd still has the balance of a fwd car 60/40 w/ driver.

Sorry, but there is no need for multiple posts of the same topic in multiple forums. In fact, as I stated to you in the other forums, it is against the rules here.
I will move this to the Mod Mania forum as it is best suited there. Todd

Well, I am under the assumption you are getting the transmission and having it shipped to you... am I wrong? as soon as you are definite on what trans you are getting I can start ordering the supporting parts... here's what we got now
Stage 2 $400 -injectors usually $200 -MAF usually $100 N02 kit $725 cams ~$300 Flywheel is usually around $125 Clutch will prob be close to $300-$400 starters usually $50 Then you have the cost of the transmission Then $2000 for the install So right now we are at $4300 plus the trans. Let me know if you still want me to investigate the nitrous controller Tom |
