I initially ignored this thread. On purpose.
Biting my tongue so hard it bled.

do i need new bumpstops also?
i read the suspension thread but i wasn't too sure if i needed em or not
Can you explain to me what exactly you did not understand?
You read this information correct?
How in the world are you "not too sure" if you need freakin' bumpstops sir?!?

Do we really need to spoon-feed you?

They used to be available from The Go Fast Depot (from the suspension sticky thread) so let me check if the shop that bought them out have them available.
Edit: Yep here they are the exact ones you need: Go Fast Depot*::*Go Fast Depot*::*Koni Bump Stops*::*High Performance Auto Parts
Is Bens answer clear enough for you? Did you even notice the source of his information?!?

17" (+) wheels suck for performance, it is more unsprung weight. More expensive tires. If you go bigger than 17" rims on a B13? Prepare to be flamed for being a total Uncle Ben's Ricer.

NOTE: Understand that some information contained in that link is...dated. This article was written by Mike before Hyperco, let alone Road Magnet springs. You have to view some of the information, specifically on commercially available springs (H&R, Eibach, etc.) and products (NuTech is out of business, etc.), in that article with a historical perspective. However, all of the rest of the info is dead accurate today, still very relevant, and it's brilliant. Like this for instance:

The widest tire that you should run unless you have a turbo or some other ungodly power is a 205. Wider tires will result in more drag than our relatively low power engines can accelerate. A 205/50-15 works well in most cases and a wide variety of R compound tires are available in this size. The maximum rim width that the B14/B15 can run is 7.5 inches with a 35-40 mm offset. A Classic B13 can run a 7-inch rim with a 30-35 mm offset as there is less wheel clearance in the rear of a B13. Since this always comes up, the bolt circle measurement on our wheels is 4x100 mm. The competition wheel that impresses me the most is the Volk TE37. This wheel is forged so it can be much thinner than a cast type wheel. It weighs a feathery 9 lbs which is twice as light as a regular wheel. The other good light wheel is the Enkei RPO-1 it weighs about 13 lbs which is still very light. Remember that 1 lb on the wheel is worth about 10 on the car due to the wheels rotational Inertia. We took 0.4 seconds off of Mike Saiki’s ΒΌ mile time just by going from 16 inch Axis wheels to 15 inch TE37’s. The difference is all in the wheel weight and tire diameter.

The Truth: Remember when you first moved up from a BMX bike to full-size mountain bike? Remember how hard it was to pedal? Gear ratio aside, it takes a lot more work to accelerate a larger diameter wheel because of the added rotational inertia. Rotational inertia (how difficult an object is to start or stop spinning) is affected by mass and radius. In the case of a wheel, the radius has an exponentially larger effect on rotational inertia than wieght alone. For example, the one inch difference in diameter between a 17- and 18-inch wheel has the same effect on the wheel's rotational inertia as increasing its weight by 10 percent at the outer radius. The effect is even greater going from an 18- to a 19-inch wheel.
Bigger wheels also weigh more. Although unsprung weight (any vehicle weight not held up by the suspension) isn't such a significant factor on the street, at the track, taking as much weight as possible off each corner will have a huge impact on lap times. The math reveals that every pound of unsprung weight is equivalent to adding 1.4 or more pounds to the chassis (sprung weight). As with rotational inertia, this effect is amplified as the wheel diameter increases.
The Fix: We don't like anything larger than 18 inches in diameter. For most smaller sport compacts, 17-inch wheels are more than enough. Look for the lightest, widest wheels that clear your suspension and fenders. If price is a limitation, sacrifice weight before width. A wide wheel means more tire and grip, but also more mass at the outer radius and therefore more roatational inertia. There is always a tradeoff. (Author James Chen).

Visually, 16's are the right size for an SE-R, but the selection of 16-inch tires is pathetic. 17's look like dubs on a B13, so we went down to the land of lightweight and abundant race rubber. The land of 15's.
Every good tire is available in 205/50/15, and 15X6.5 and 15X7-inch wheels are abundant in the bolt pattern (4X100mm) and offset (+35mm) the SE-R requires. (Author Dave Coleman)
Check this thread for wheel weights:
wheel weights - 3000+ brands - SR20 Forum It links you to a web-site that lists wheel weights for 3,000+ rims.
Conversion Tables for Rims and Tires You want to +1 your rim size and keep your speedometer as accurate as possible? Thank you Canx2k for this excellent thread:
Conversion table for bigger rims/tires - SR20 Forum
Where should I buy tires? Well, you should always check Tire Rack. They offer great service, support, pricing, and an uber-cool web-site: Tires Their web-site allows you to view different rims on your vehicle. Their tire buying process has tons of information and reviews on tires.
How old are my tires, even when new? Yes, tires have a have a shelf-life.

Thanks to forum member 97 SR20 for that information. And for sr20jet for the Reader's Digest version:

Further, according to an ABC News report in the thread link, tires can start to deteriorate at the four (4) year mark, and become dangerous at the six (6) year mark. However, tires have no "expiration date" at the tire dealers. Make sure you are buying relatively new tires and not a tire that has been sitting on a shelf somewhere for five (5) years.
Stock OEM wheel information for the B13 and B14. What is the size, offset, bolt pattern, center bore, weight, and how does changing my rims change my speedometer accuracy?

Which tires are SR20-Forum Members running on their street or track cars, and what is their opinion on the tires?
From Cliff, this thread covers all the Forum Member reviews of tires in great detail.

Did you miss
that entire section as well as the section on bumpstops?
You skimmed the Cliffs Notes version of my thread down at Barnes and Nobles?
You require more than eight (8) threads linked, on the

This entire thread you created is a complete and total waste of time.
We are spoon feeding you answers, and posting pictures, and leading you by the hand...through the gawd-damned information in the Suspension Thread.
Every single question you have asked in this ridiculous thread of yours, and
every single answer to those ridiculous questions, is IN FACT answered in the Suspension Thread.
This is utter nonsense. There is no lack of information. There is only
your lack of reading or reading comprehension sir.
YOU need to go READ THE SUSPENSION THREAD. Again.
