450 left front spring on smack down

[tin man]

Not every car has the roll center far enough to the right to run a 275 or less on the RF. A smack down for one doesn't

I would have to disagree with that statement. It can be done and it can be successfully done.

Tin man his car is way before they raised the cross member , with a 275 or less that car would bottom out something fierce unless your racing on a track that only allows 50 mph entry speeds. Or you have a bump stop or you have a really old school spring that coil binds before the car bottomed out. A Gen x car has the roll center way to the right and the additional clearance to run that soft. But hey springs aren't very expensive so if you really want to try a 225 on the rf of a smack let us all
Know how it works .

Our car is a '10 Smack. Nothing fancy. Raised frame rail. Standard crossmember. Run steel block late model. Have won a 1k race earlier this season at Winchester and set third fastest time at the Steel Block Bandit race at Eastside Sunday and finished fifth in the feature. Run Hagerstown regularly also which isnt exactly a stop and go track. I never said 225. You did.

They starting raising the rail in 09. My 08 smack earned its " smack down " nick name with any less than 350 rf

this is completely off subject but if anyone is running a 275 or softer on the rf without doing something else with it and your doing great,put some drive back in it and lap everyone,jmo

Yea but the dude said he was trying to free up entry and said he was 400 rf. It's pretty simple the softer you are on the right front the better your gonna steer.
You just have to find out at what spring rate you start to bottom out at, I know a lot of guys that start out on 300s and go to 250s and 225 as the night goes.

not on entry the car will be tighter on entry(so it doesn't steer better it pushes)
any time you go softer on the rf its going to be tighter in and free off
unless you do more than just a spring change
remember shocks can have an effect too
and I'm talking about just a standard spring setup nothing else

I have seen where a softer rf loosened car, on a track that was heavy, and the driver could stay in the gas past the entrance. But, generally a softer rf de-wedges the car, off the gas, and transfers more weight to rr, thus making the car tighter.

like i have said tighter entry,looser exit(or on the gas)
if your at a track where you can stay on the gas on entry,yes if you soften a spring it will free it up but those tracks are very few,i can only think of two

Just something I've been thinking about... what happens in theory to a DLM when you go from a 450/350 front spring setup to say a 475/325 front spring setup? I've been considering doing some spring testing eventually to understand what combinations produce better results.

the car will be free in and tighter off with the 450/350 and the opposite with the 475 and 325
